Abstract
Cd(II)-ion-selective electrodes (Cd(II)-ISEs) were developed on the base of chalcogenide glasses (ChGs) from the GeSe 2–Sb 2Te 3–CdSe system. Novel constructional designs of the “coated wire” type were created consisting of an inner Ag/AgCl reference electrode uniformly coated with a composite mixture of a binding polymer and Cd-containing ChG powder. Cd(II)-ISEs were tested with respect to their basic analytical characteristics: stability, linearity (L, mol l −1) and slope (S, mV dec −1) of the electrode function, working pH-range, limits of detection (LD, mol l −1), response time ( τ 95, s) and selectivity coefficients ( K i , j pot ) in the presence of ions, which commonly accompany Cd 2+-ions in the analytical media.
