摘要：

This paper presents a first report on an ammonium ISFET (ion-sensitive field effect transistor) based on a polymeric membrane (siloprene) including a zeolite selective for ammonium exchange: clinoptilolite. The effect of zeolite content on sensitivity of detection is studied; an optimum is obtained for 43 w/w%. A sensitivity of detection of 32 mV/pNH(4)(+) and a detection limit of 10(-8) M are obtained. A highly selective ammonium ISFET is obtained. (C) 2002 Elsevier Science B.V. All rights reserved.
