Simultaneous determination of the toxic trace metals Cd, Cu, Pb and Zn in soils by differential pulse anodic stripping voltammetry



Simultaneous determination of the toxic trace metals Cd, Cu, Pb and Zn in soils by differential pulse anodic stripping voltammetry



Fresenius Zeitschrift fur Analytische Chemie 313(5): 390-394



The method described is based on differential pulse anodic stripping voltammetry at the hanging mercury drop electrode in the analyte. Pressurized wet digestion of the finely powdered soil in a mixture of HNO3-HCl, optionally followed by UV irradiation to decompose dissolved organic matter, was used to prepare the analyte. Twelve soil samples from various polluted and unpolluted regions in West Germany and the Netherlands were analysed.
