Sulfide-selective electrodes based on the sulfided monocrystals of CdSb

A method of formation of the sulfide-sensitive electrodes in the water-free superbasic solutions using the sulfided semiconducting CdSb monocrystals has been investigated. The effective range of the sulfide ions concentration was found and some other conditions were determined in order to ensure formation of the electrodes with the linear potential/sulfide concentration characteristics. Using the atom absorption spectrometry, the 6:1 molar ratio was found for the Cd and Sb atoms concentrations in the surface electrode film.
