It is rare indeed that one comes in contact with a process or technique which impacts many technical disciplines. Ion exchange is such a processs. Although many books have been written on the topic of ion exchange, most have been aimed at the specialist and the graduate engineer or chemist. The author's experience in ion exchange technology has indicated that there are many specialists in the industry who do not understand ion exchange as a process. Therefore this manual has been written to aquaint and to train. The author has provided background information and hands-on experimental units that can be used to train laboratory technicians who later become assets in the industry. This material has been used by the author for in-house training and at the community college level with success. It is my sincere hope that the training obtained in this manual will, in some way, be used to improve the environment in which we live. Ion exchange technology has the potential to reduce pollution and improve water supplies when applied properly. In writing this manual I have had the benefit of valuable assistance. I am indebted to Wes MacGowan and Dr. F. X. McGarvey for helpful suggestions and continued encouragement to get the job done. I have also learned much over the years from Dr. S. Fisher, D. R. Kunin, and Dr. I. Abrams. In one way or another they too have some influence, however indirect, on this modest effort.
