摘要：

A solid-state ion selective electrode, which is sensitive to hydroxide ion concentration has been prepared. This electrode with a 10% Cu2S and 90% Ag2Se composition exhibited an analytically useful potential change from 10(-6) to 10(-1) M hydroxide ion, pH 8-13. The slope of linear portion is about 58 mV per decade change in hydroxide concentration. There was no interference of K+, Na+, Ca2+, Zn2+ and Mg2+ cations and Cl-, NO3- and SO42- anions. The response time was 30 s and the lifetime was about 2 years. (C) 2004 Elsevier B.V. All rights reserved.
