Preface
This volume contains the papers presented at the Sixth International Ion Exchange
Conference organised by the SCI and held at Churchill College, Cambridge, UK, in
July 1992. As on previous occasions, most recently in 1988, the organising
committee did not engage plenary speakers but decided to solicit state-of-the-art
contributions from the ion exchange community. This book contains the refereed
papers presented at the meeting, whether in poster or oral form. Extra papers were
presented at the meeting as posters because they were not available in time for
refereeing purposes.
The subject matter of the meeting and therefore the contents of the book is
subdivided into seven separate topic areas as follows: resin developments; water
treatment; fundamentals; biotechnology, food and pharmaceuticals; environmental
and pollution control; membranes, inorganic materials and nuclear; and
hydrometallurgy. The coverage of the meeting is similar to 1988 although there are
fewer subdivisions on this occasion. The more restricted coverage this time reflects
the smaller number of papers offered by authors. This is probably due to the world
wide industrial recession which has affected commercial development and
exploitation of the technology and restricts the ability of practitioners and
academics to contribute to and attend international meetings. Nevertheless, the
advances in biotechnology, growing concern about the environment and the.need
for novel separation processes have provided sufficient impetus to stimulate a
sufficient number of workers in the field. Original contributions in the fields of
hydrometallurgy, nuclear technology and inorganic materials are less evident at this
conference and this is possibly because these topics have reached a level of maturity.
There is a striking absence of papers concerning chemical applications and catalysis.
This is surprising since it is a dynamic field but possibly rather too close to the
market and therefore subject to confidentiality. That is unfortunate if it is the case.
Three outstanding contributors to the subject of ion exchange were honoured by
the SCI Solvent Extraction and Ion Exchange Group at the meeting: Dr T. V. Arden
was recognised for his contribution to the science and industrial application of ion
exchange, Dr F. Martinola for his work on resin developments and Dr D. E. Weiss
for his innovative contribution to ion exchange technology.
A meeting of the size of lEX '92 can only be organised with the willing help of a
committee of volunteers supported by their companies and universities. The
Chairmen wish to express their gratitude to the following: Kevin Blaxall, Howard
Chase, Harry Eccles, Jim Greig, Michael Sadler, Bob Scott, George So It and
VI
Michael Verrall. We are also indebted to many other people who helped to make the
work-load bearable, in particular our session chairmen and referees who facilitated
the production of this book. The staff at SCI, in particular Anne Potter and
Monique Heald, have played a large part in creating lEX '92.
