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.
