摘要：
The copper cathodic stripping peak obtained in hydrochloric acid medium by fast differential-pulse potential scanning in the negative direction was studied. Conditions for the simultaneous determination of Pb, Cd and Cu by combined stripping voltammetry (anodic for Pb and Cd and cathodic for Cu) were found; copper was actually determined by adsorptive voltammetry. Samples of CaHPO4 and CaCO3 were analysed by the proposed method and the relative standard deviation for 10(-5)-10(-4)% metal contents was about 8%. The accuracy of the results was confirmed by extraction flame atomic absorption spectrometry.
