Recent Developments In Ion Exchange

These Conference Proceedings deal with the papers presented at the International Conference on Ion Exchange Processes (ION-EX '87) which was held at The North East Wales Institute of Higher Education, 13-16 April 1987. The camera-ready paper format was chosen so that delegates could receive their copy on arrival at the Conference. The Proceedings include reviews of traditional ion exchange processes, ion chromatography and synthesis of resins. In addition there are research papers dealing with inorganic ion analysis; organic acid and organic base analysis; the theory of ion exchange and novel developments; the industrial ion exchange procedures; and finally inorganic ion exchangers. The Proceedings should therefore be of interest to those who need to be brought up to date in the various aspects of processes which involve ion exchange and ion chromatography which are now accepted as important in analysis, separation processes and process control. In each of these areas there have been important developments which are herein described. As Editors we should like to express our thanks to the individual authors for preparing their manuscripts in the required format and to Haydn Hughes for his invaluable assistance in compiling these Proceedings.
