Abstract
The influence of surface active substances (SAS) (Triton X-100, sodium dodecyl sulfate and dodecyl pyridinium chloride (DPC)) on the potenti ometric stripping analysis (PSA), square-wave voltammetry (SWV) and an odic stripping square-wave voltammetry (ASSWV) of Cd2+, Cu2+, Zn2+ and Bi(III) are measured for various contact times and detergent concentr ations. Diagnostic criteria for the presence of SAS in electrolytes ar e reported. Zinc ions accumulate in the adsorbed layer of DPC, probabl y as a ZnCl+ complex. An anomalous dependence of zinc SWV peak current s on the delay time is observed.
