Concentrated treatment of all aspects of technology and handling directly related to the products of electrolysis. Thoroughly up to date and should become the standard reference in its field.

The book addresses the latest technical developments in the chlorine industry with emphasis on operational improvements. The effects of economic, political, environmental and safety issues surrounding the industry are covered.

The papers in this book were submitted for the 1988 London International Chlorine Symposium. This was the fifth symposium organised by the Electro chemical Technology Group of the Society of Chemical Industry and proved as popular as ever, attracting a record number of 294 delegates from 31 countries. Twenty-seven papers were presented during the two and a half-day event covering the latest developments in chlor-alkali technology. The field of membranes and membrane cells was well represented by some 15 papers, reflecting the importance of membrane technology to the future of the industry. This is particularly relevant in view of increasing environmental pressures and rising costs. However, papers relating to the more traditional mercury and diaphragm cell technologies were also presented, together with a paper concerned with sodium chlorate manufacture. In addition, there were presentations covering the commercial and safety aspects of the chlor-alkali industry. The Electrochemical Technology Group of the Society of Chemical Industry offer thanks to the many people and organisations whose help ensured the success of this symposium. In particular, we would like to thank: 1. The contributors of the papers. 2. The session chairmen: Dr R. G. Smerko (The Chlorine Institute Inc.); Mr B. Lott (The Associated Octel Company Limited); Mr T. F. O'Brien (United Engineers and Constructors); Dr B. S. Gilliatt (ICI Chemicals and Polymers Limited); Mr D. Bell (Hays Chemicals Limited). 3. The Chlorine Institute for assistance with printing costs and for active participation.

It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M.

White Preface to Volume 2 This volume brings together some dozen processes well known to the electro chemist and treats them according to their various degrees of importance. The production of hydrogen is one of the more important processes, particularly with respect to the prospects of a hydrogen economy. No one would doubt, however, that the most commercially important electrochemical processes at the present time are the production of aluminum and of chlorine. Each of these processes has a separate chapter devoted to it.
