The pigment anddye industry has had to develop the technology necessary to analyzeand remediate pollutants in wastewater.
Although these efforts haveproduced a considerable volume of information, until now, no singlebook has provided an organized, comprehensive treatment of theenvironmental chemistry of synthetic colorants. Environmental Chemistry of Dyes and Pigments is the firstcomprehensive reference to address the environmental problems posedby synthetic colorants, and to provide a forum for the solutionsproposed by industry, government, and academia. Focusing ondevelopments in the field over the past two decades, it deals withall aspects of colored wastewater treatment, the disposal of dyes,analytical methods, toxicity, and regulatory questions. In its coverage of wastewater treatment, this book addresses boththe most commonly used methods and those specifically designed toaddress pollution problems at the source by analyzing for andremoving dyes and pollutants from wastewater effluent.
Throughout,real-world data on a wide variety of dyes and dye intermediates isprovided, as well as cost-effective strategies for dealing withwastewater treatment. In addition, several chapters are devoted to the perspectives ofnational and international experts on regulations governing themanufacture, handling, use, and disposal of synthetic dyes andpigments. The impact these regulations have had on both U.S. Andforeign industry is also discussed. A complete, comprehensive, and up-to-date guide to pollutionprevention in the dyestuff and textile industries Environmental Chemistry of Dyes and Pigments is the onlyself-contained volume that focuses on the environmental impact ofsynthetic dyes and pigments. Contributions by international expertsfrom industry, academia, and government make this an indispensablebook for anyone dealing with the environmental problems posed bysynthetic colorants.
It covers the entire range of environmentalissues, from waste treatment and analysis to pollution preventionand government regulations. Author by: H.

There are two types of colorants dyes and pigments. Dyes are soluble substances used to pass color to the substrate and find applications primarily in textiles and leather. Pigments are coloring materials, which are water insoluble. Key end-user industries of pigments include wood-coloring, stone, textiles, paints & coatings, food and metals. Pigment are usually manufactured as dry colorants and grounded into fine powder. The dyes market, meanwhile, largely depends upon the fortunes of its principal end-user, textiles, which account for about 70 percent of the total demand.
Their importance has grown in almost every area of an economic activity. In the colorants market, Asia-Pacific accounts for the largest share. This region is one of the key markets for dyes and pigments production. In the Asia-Pacific, India and China are the important countries contributing towards the growth of colorants market. Rising consumer spending will drive increased demand for colorants in textiles. Increases in value demand will reflect the growing importance of expensive, higher value dyes and pigments that meet increasingly stringent performance standards.
Growing demand for high-quality value-added pigments is one of the key factors expected to result in a spurt in growth. This book describes the various formulae, manufacturing processes and photographs of plant & machinery with supplier’s contact details. The major contents of the book are metal pigments, black pigments, inorganic colour pigments, organic colour pigments, extender pigments, white pigments, photocatalytic activity of titanium dioxide pigment, azo pigments, bisazo pyridine pigments, high grade organic pigments, high temperature stable inorganic pigments, anti corrosive pigments, metals and metal ions in pigmentary systems, control of organic pigment dispersion properties, pigments for plastics, rubber & cosmetics, pigments for printing inks, vat dyes, reactive dyes, disperse dyes, direct dyes and sulphur dyes etc. It will be a standard reference book for professionals, entrepreneurs, those studying and researching in this important area and others interested in the field of textile dyes & pigments.

The majority of natural dyes are vegetable dyes from plant sources.
Dyeing is the process of imparting colors to a textile material. Different classes of dyes are used for different types of fiber and at different stages of the textile production process, from loose fibers through yarn and cloth to completed garments.
There are technologies that manufacture the pigments for plastics, rubber and cosmetics. Therefore; dyes and pigments have a vast area of applications and have a huge demand in industry. Contrary to popular opinion, natural dyes are often neither safer nor more ecologically sound than synthetic dyes.
They are less permanent, more difficult to apply, wash out more easily, and often involve the use of highly toxic mordant. Of course, the colour possibilities are far more limited; the color of any natural dye may be easily copied by mixing synthetic dyes, but many other colors are not easily obtained with natural dyes. However, some mordant are not very toxic, and the idea of natural dyestuffs is aesthetically pleasing.
Applying natural dyes in your fabric production using enzymes will reduce your production cost and improve control. There are various kind of natural dyes; quinonoid dyes, cyanine dyes, azo dyes, biflvonyl dyes, omochromes, anthraquinone, coprosma gesus etc. The use of natural dyes in cloth making can be seen as a necessary luxury to trigger off a change in habits.
Dyes which stand out for their beauty and ecological attributes would never be employed on just any material but on noble fabrics such as wool, silk, linen or cotton, made to last more than one season. Market value will benefit from consumer preferences for environmentally friendly products, which will support consumption of high performance dyes and organic pigments. Author by: Arnold R.

The term colorant is often used for both dyes (also called dyestuffs) and pigments. The major difference between dyes and pigments is solubility (the tendency to dissolve in a liquid, especially water). Dyes are usually soluble - or can be made to be soluble - in water. Once a dye is dissolved in water, the material to be dyed can be immersed in the dye solution. As the material soaks up the dye and dries, it develops a colour. If the material then retains that colour after being washed, the dye is said to be colourfast. Pigments are generally not soluble in water, oil, or other common solvents.

To be applied to a material, they are first ground into a fine powder and thoroughly mixed with some liquid, called the dispersing agent or vehicle. The pigment-dispersing agent mixture is then spread on the material to be coloured. As the dispersing agent dries out, the pigment is held in place on the material.
In most cases, dyes are used for colouring textiles, paper, and other substances, while pigments are used for coloring paints, inks, cosmetics, and plastics. This book presents new and significant research from around the world in this field.

Today, there are numerous options and methods for the colorization of textiles.
While todays methods capitalize on efficiency, there is question as to whether the use of chemicals is harmful to the environment. A reputation for harming the earth could be detrimental to a company in a society becoming more and more focused on the environment and its preservation.
Today, with the invention of synthetic materials used in textiles, many new types of dyes have been developed and put into regular use. There are two basic ways to color textiles: dyes and pigments. Pigments are not a dye but rather resins mechanically bound to fibers. Dyes are divided into classes according to the types of fibers they are most compatible with. Textile printing is related to dyeing but, whereas in dyeing proper the whole fabric is uniformly covered with one color, in printing one or more colors are applied to it in certain parts only, and in sharply defined patterns.Dyes will yield the softest hand (the 'hand' is the feel of the fabric) and maintain the fabric's luster but the process is expensive. Pigments are much more economical to use. Pigments are generally more lightfast, more colorfast, and give greater color control.
Pigment technology has developed tremendously in the past 15 years. 85% of the textile printing in the World is pigment printing.This book contains manufacturing process and other related details about Azine dyes, Azoic dyes, Azo dyes, Thiazole dyes, Triphenylmethane dyes, scientific classification of Vat dyes, fluorination of dyes, different types of pigments, applications, usages of dyes and pigments, quality control and evaluation of pigments and many more. This book will serve as a guide to Textile Technologists, Scientists and existing as well as upcoming industries.

Reflections of a Successor to Dr. Zollinger Lany C.
Carey, MD,’ Columbus, Ohio Dr. Hiram Polk asked that I contribute a piece for this issue of the Journal honoring Dr. Robert Zollinger. It is a great pleasure to do so, but in many ways a more difficult assignment than writing a scientific paper. I recognize that the invitation may in fact have been influenced by Dr. Polk’s reading of some of my previous scientific papers. His request was specific.
He asked for my reflections on succeeding Dr. There is a bit of irony in the timing. When the request arrived, I had just returned from two informative and restful months in Europe with a clear and considered decision to resign from the chairmanship of the department of surgery at Ohio State after 11 years. I had, as often before at critical times, discussed my plans with Dr.
Zollinger before making the final decision. This rather important step in my life made the review of the past decade and my relationship with Dr. Zollinger an interesting and timely chore. The early fall of 1974 was an eventful time for me. I was invited by the dean at The Ohio State University College of Medicine to succeed Dr. Robert Zollinger as chairman of the department of surgery. Having attended medical school at Ohio State, I was particularly thrilled to be asked to chair a department there.
To students at Ohio State, Dr. Zollinger was the most memorable member of the faculty.
Generally he was gentle to medical students, in contrast to his celebrated acerbity with residents. He was, however, a formidable professor who challenged and stimulated students. The clinical clerks on his service were made to feel they were an important part of the house staff team. We were expected to be totally informed about the patients to whom we had been assigned. Our duties included preoperative and daily postoperative calf measurements and vital capacity assessment. We were also expected to know all laboratory data, as well as all pertinent. Robert M.

Zollinger Profess of Surgery. The Ohio State University College of Medicine, Columbus, Ohio. 676 facts of the history and physical examination of each patient, and the total volume of fluid losses, as well as the electrolyte content of intake and output for the previous 24 hours. In all patients receiving intravenous fluids, we performed urinary chloride tests each morning. When one of our patients went to the operating room, we were required to draw the relevant anatomic characteristics in colored chalk on a blackboard outside the operating room. Any dereliction of duty by a medical student was always construed by Dr.
Zollinger to be the fault of the resident staff. What all of this accomplished, of course, was enormous attention to patients by students, as well as a forced camaraderie of students and residents. It was a very effective system. All of this activity took place on 7 East of The Ohio State University Hospital. Zollinger came to Ohio State in 1946. He had attended medical school at Ohio State and began his training at Boston’s Peter Bent Brigham Hospital in 1928, continuing with Dr.
Elliott Cutler at Lakeside Hospital in Cleveland from 1929 to 1932. He returned with Dr.
Cutler to Harvard and the Brigham Hospital in 1932, where he finished his training and stayed on the staff until World War II. He returned to Harvard after the war and accepted the position at his alma mater 2 years later. When he came to Ohio State, the University Hospital was a very small facility called Starling-Loving Hospital.
The residency program was fragmented, and there were three parallel residencies and two departments of surgery. Zollinger practiced at most of the hospitals in the city and maintained an office for his practice in a downtown building.
The hospital facilities at the University consisted of an 150 bed adult hospital for the entire clinical faculty. This situation prevailed until late 1951, when the present University Hospital opened. As a freshman being oriented to the campus in September 1951, I was taken on a tour of the new, nearly completed hospital. As soon as the new hospital opened, Dr.
Zollinger was able to centralize the residency program in one The American Journal of Surgery Salute to Robert M. Zollinger, MD institution and to focus his practice at University Hospital. From his appointment in 1946 until his retirement in 1974, Dr. Zollinger’s career was characterized by leadership and visibility in his field. Few men have been more widely recognized by their peers than he. Table I lists the major posts he has held in major societies.
Table II lists the major awards and prizes he has received and attest to his wide recognition both at home and abroad. The prospect of succeeding a man of such singular accomplishment was indeed intimidating. In January 1975, I moved back to Columbus after 15 years of absence and assumed the post of chairman of the department. For many months, I rather expected Dr. Zollinger to suggest that I vacate his office. The office is one I had visited on occasion as a student., and it looks out on the open end of the football stadium.
To a certain degree, it was ther. And is still Dr. Zollinger’s office. Our patients were housed on the same unit in the hospital. It was 7 East, the place where I had served my clerkship 15 years earlier.
There is a small conference room at the rear of the nursing station, and there, usually on Sunday morning, Dr. Zollinger and I visited over coffee. (I have always called him Dr. Zollinger and could no more use his first name than I could call my father by his first name.) Those Sunday morning visits were memorable. Free from the press of office duties and the telephone, we could talk without interruption. The range of topics was broad, but always liberally seasoned with reminiscences of Dr.
Cutler and the Brigham Hospital and war experiences. I learned an enormous amount about the early days of the American Board of Surgery; there were colorful and unrepeatable accounts of the American College of Surgeons and the American Surgical Association; and there was often sound and gently given advice about national surgical politics and about local issues in the College of Medicine and the department. Zollinger has a unique response to requests for advice. He begins with observations that may seem remote from the topic at hand. As his thoughts develop, he considers various aspects of the issue and plays verbal ping-pong, considering first one side of the issue and then the other. In the end, you will make a decision and will have been advised in such a way that no matter what the result, he can say, “I told you so.” The advantage is that, in listening to him analyze the situation, aspects that you had never considered often emerge. Zollinger has no peer as a moderator of panels.
Surgical grand rounds provided a local forum for his unique talent and always played to a full house at Ohio State. It was an opportunity to watch the master at work.
It was always entertaining, always informative, and there was always banter between Dr. Zollinger and the residents who presented the cases.
