Electrochemical Formation of a Novel Conducting Polymer Membrane on CPE from Aqueous Solution Containing Pb (II) Acetate

摘要

A membrane was synthesized to prepare a selective electrode to Pb(II) based on a complex Pb(II)-acetate: the effects of experimental conditions on the synthesis were analyzed, like that of the potential range used and of the lead and acetates concentration in solution were investigated during the formation process of the surface film. The lead concentration had a direct effect on the current's response. The process of electrochemical formation of the film was found to be directly dependent on the lead-acetates species predominating in solution.
