Disturbance of a Film of Triton X-100 on the Hanging Mercury Drop Electrode during the Determination of Metal Ions by Anodic Stripping Voltammetry

Abstract

The effect of electroreduction of Zn(II), Cd(II), Pb(II) and Cu(II) ions on the stability of a film of the surfactant Triton X-100 on the surface of hanging mercury drop electrode was investigated. A procedure is suggested to disturb the film in order to facilitate the determination of the above metal ions by anodic stripping voltammetry with accumulation.
