The parameters of the specific electroconductivity and electrode properties of massive glass and amorphous films of PbS–AgI–As2S3 and PbS–Ag2S–As2S3 are studied. It is established that the lower detection limit of Pb2+ cations is 10–7 mol/L for most of the studied membranes, while the Nernst region of the electrode function is 10–6–10–1 mol/L. The response time of the best film membranes Pb-ISE is 30–40 s in diluted solutions and 5–10 s in 0.01–0.1 M stirred solutions of Pb(NO3)2.
