摘要:
A procedure for simultaneous determination of chromium, nickel and selenium in their model mixtures, using adsorption stripping voltammetry (AdSV) for chromium and nickel and cathodic stripping voltammetry (CSV) for selenium is proposed. The effect of the adsorption time, pH, presence of possibly interfering anions, molar ratio of Cr, Ni and Se and the order of their determination in solution on the sensitivity peaks was examined. By a suitable choice of all these parameters, a simultaneous determination of the mentioned elements by voltammetric techniques in model mixtures was achieved.
