Abstract

The preparation conditions and the performance of a small size Ag/Ag2S selective electrode are described. The analytical behaviour of this electrode, made by chemical treatment of a silver wire, is described in terms of potential - concentration curves, standard potential, lifetime and electrode selectivity. A series of electrodes have been prepared and investigated. Their response and selectivity to Ag+ and S2- are measured and compared with those of a commercial Orion silverlsulfide electrode. Several titrations were performed to evaluate the performances of the electrode. The investigated electrode can be used, as a good substitute for the commercial silverlsulfide electrode, in a wide variety of practical analytical systems.
