Аннотация:The parameters of specific conductivity and electrode properties of massive glass and amorphous films PbS-AgI-As2S3 and PbS-Ag2S-As2S3 have been studied. It was found that for most of the studied membranes the lower limit of detection of Pb²⁺ cations is 10-7 mol/L, and the Nernst region of the electrode function is 10-6-10-1 mol/L. The response time of the best Pb-ISE film membranes is 30-40 s in dilute solutions and 5-10 s in 0.01-0.1 M Pb(NO3)2 solutions under stirring.
