The second edition of Ion-Selective Electrodes contains a survey of the theory and applications of ion-selective electrodes based on the literature published up to mid-1981. Because of the rapid progress in the whole field and the very large amount of diverse data, a compact and unified treatment of the theory has been attempted. The technology and the applications have also been updated. In view of these facts we have had to write practically a new book. In contrast to the first edition, only a selective list of references could be included in the book, because otherwise we would have to deal with more than four thousand references.

We are grateful to our colleagues Professor J. Dvořák (Faculty of Science, Charles University, Prague), Dr J. Bureš (The Institute of Physiology, Czechoslovak Academy of Sciences, Prague), Dr J. Veselý (The Geological Survey, Prague) and to Dr Z. Samec (The J. Heyrovský Institute of Physical Chemistry and Electrochemistry, Czechoslovak Academy of Sciences, Prague) for valuable suggestions during the preparation of both editions of the book. The Czech manuscript has been translated into English by Dr M. Hyman-Štulíková. We would also like to thank Dr A. Kejharová, Mrs M. Kozlová, Mrs D. Tůmová and Mrs L. Korytová for their help with the preparation of the manuscript.
