Abstract

The response of copper(II)-selective electrodes based on copper(II) sulphide incorporated in silicone rubber or compressed to pellets is described, with particular reference to electrode behaviour after treatment with various oxidizing agents and regeneration by chemical procedures. Changes in the surface state of the membranes were examined by electron microprobe analysis and photoelectron spectroscopy. The electrochemical behaviour of the membranes can be correlated with surface morphology changes, primarily connected with formation of sulphate monolayers.
