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 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.

The objective of this second edition remains the discussion of the many diverse roles of electrochemical technology in industry. Throughout the book, the intention is to emphasize that the applications, though extremely diverse, all are on the same principles of electrochemistry and electrochemical engineer based ing. Those familiar with the first edition will note a significant increase in the number of pages. The most obvious addition is the separate chapter on electrochemical sensors but, in fact, all chapters have been reviewed thoroughly and many have been altered substantially. These changes to the book partly reflect the different view of a second author as well as comments from students and friends. Also, they arise inevitably from the vitality and strength of electrochemical technology; in addition to important improvements in tech nology, new electrolytic processes and electrochemical devices continue to be reported. In the preface to the first edition it was stated: . . . the future for electrochemical technology is bright and there is a general expectation that new applications of electrochemistry will become economic as the world responds to the challenge of more expensive energy, of the need to develop new materials and to exploit different chemical feedstocks and of the necessity to protect the environment. The preparation of this second edition, seven years after these words were written, provided an occasion to review the progress of industrial electro chemistry.
