Abstract
Various simultaneous effects of humic acids on the current and potenti al of differential pulse anodic stripping peaks of copper, lead, cadmi um and zinc in weakly alkaline and acidic (pH 2) solutions have been i nvestigated and interpreted with regard to metal complexation and the adsorption of humic acid on the mercury electrode. The applicability o f the standard additions method for metal quantitation and the experim ental conditions for UV-photolysis with a high-pressure mercury lamp h ave been examined in model as well as real water samples.
