Abstract

A series of chalcogenide glasses of various compositions, based on the TlI–Ag2S–As2S3 system, were prepared. The conductivity parameters and diffusion coefficients of silver and thallium radiotracers in the glass samples were determined. Chemical sensors with membranes of four glass compositions were prepared, and their analytical characteristics (sensitivity, selectivity, detection limit) were studied. Correlation between the ionic conductivity parameters of the ion-sensitive membranes and the analytical characteristics of chemical sensors for thallium ions in solutions was found.
