Zeolite-modified electrodes in electroanalytical chemistry

This review reports on the analytical applications of chemically modified electrodes involving zeolites or zeolite-like materials. After a brief introduction on zeolites, the implication of these solids in electrochemistry is discussed. The interest of zeolite-modified electrodes (ZMEs) for electroanalytical purpose is pointed out, by classifying the applications into five main categories depending on the detection process. In the last decade, successful applications of ZMEs have been achieved. This promising field is thought to lead to significant advances in the near future, because of the explosive growth in the synthesis of never zeolite-like materials. (C) 1999 Elsevier Science B.V.
