| 摘 要： | Anodic stripping voltammetry (ASV) is an effective electroanalytical technique for themeasurement of trace metal ions. But there are serious interferences due to overlappingstripping peaks and forming of intermetallic complex in complicated system. The peak ofcopper (ASV) is close to that of mercury. So the result of determination of copper is notsatisfactory. Adsorption chronopotentiometry was reported by H.Eskilsson et al i. In thismethod, instead of electrolytic accumulation of metal io…

| Abstract: | The behaviour of the complexes of copper,lead,cadmium and antimony with salicylfluorone (SAF) adsorbed on HMDE has been investigated by derivative chronopotentiometry in NH_3/NH_4C1. The dependence of the peak height on the dt/dE vs E curve on preconcentration time, the pH of solution and the constant reducing current are discussed. This method achieved the simultaneous determination of copper, lead, cadmium and antimony in human hair. |
