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.

The papers in this volume were presented at the 1991 London International Chlorine Symposium held at the intercontinental Hotel from 5th-7th June. This was the sixth symposium in a series organized by the Electrochemical Technology Group of the SCI and held in London at intervals of three years. A continued high level of interest in the proceedings was demonstrated by offers of 40 papers, and of these 26 were selected for inclusion in the programme. The conference intention was to reflect the developments in chlorine technology hardware and software and to address the economic, political, environmental and safety issues which are increasingly impacting on the chlorine industry as the millennium approaches. In the event the five sessions were broadly based on the following topic areas: Chlorine and the Environment Membranes 1 Membranes 2 Chlorine Safety Electrodes/Electrode Reactions Not unexpectedly, the importance of membrane technology to the industry was reflected by the inclusion of 9 papers. However, the traditional diaphragm, mercury and chlorate cell technologies were also represented. The academic base of the organizing body was underlined by the selection of papers from the Universities of Milan and Calgary, and by the opening and closing remarks of the Chairman of the SCI Electrochemical Technology Group, Frank Goodridge, Professor Emeritus of Newcastle University. The opportunity was taken to present the SCI Castner Medal to Dr H. Miyake of Asahi Glass Co. Ltd for his work on the design and development of Flemion electrodes.
