摘要
Zn(II) ion-selective electrodes with chalcogenide glassy As2Se3–Sb2Se3–ZnSe and GeSe2–ZnSe–ZnTe membranes were developed. Basic analytical characteristics such as stability, linearity, slope of the electrode function, limits of detection, effect of pH on the electrode potential and response time were studied with varying glass compositions. A structural mechanism for explanation of the dependencies obtained is suggested.
