摘要：

Information on the transition metals content in natural waters is of great environmental interest. The procedures presented in this paper deal with the simultaneous determination of copper, cadmium, lead, and zinc in 0.05 M nitric acid (0.05 M HNO3 + 0.1 M CTRAc) 0.1 M citric acid by differential pulse anodic stripping voltammetry or differential pulse polarography; manganese, nickel, and cobalt were determined in ammonia/ammonium acetate buffer at pH 9.1 by differential pulse anodic or cathodic stripping voltammetry, titanium and relevant iron concentrations by pulse polarography in 0.2 M oxalic acid in the presence of 0.1 M potassium chlorate. The voltammetric schemes and response are critically compared to Zeeman graphite furnace atomic absorption spectrometry.
