N2 - Electrode properties of chalcogenide glasses of composition xAgI-(1-x)Sb2S3, where x = 0.3-0.6, were studied with the aim to develop a multisensor system for the direct potentiometric determination of heavymetal cations and inorganic anions in natural and waste waters. It has been found that these glasses are sensitive to hydrogen and heavy metal (Cu, Pb, Cd, and Zn) ions; the higher the AgI concentration in the glass, the higher its sensitivity to these ions. It has been shown that a multisensor system constructed from an array of chalcogenide glass sensors can be used for determining heavy-metal cations and inorganic anions in aqueous solutions, including Zn2+ and SO42- ions, whose ion-selective sensors are absent in the array.
