✦ Synopsis
Nitrate-selective ion-sensitive field effect transistors (IWETs) were prepared by dip-coating the silica gate insulator surface with an ion exchanger based on bis(bathocuproin)-copper(I) nitrate dissolved in a molten mixture of docosan-l-o1 and triphenylphosphate. This sensor showed a linear response from 10-l mol dmT3 to at least 10e5 mol drn-and maintained its response characteristics for as long as 5 weeks. The selectivity sequence for common anions such as ClOi and Cl-followed the conventional Hofmeister series. This sensor was applied to rain water analysis.
