Abstract: Anew method for determination of trace palladium by anodic stripping-catalytic voltammetry has been established.The Pd(Ⅱ) was deposited with Hg (Ⅱ) on aglassy carbon electrode in NaCl-HCl-HgCl2 base-solution at -0.80Vfor several minutes.After the depositing, the glassy-carbon electrode was removed itno another cell containing a catalytic system, HClO4-HCl-SnCl2.Astrippihg-catalytic peak of Pd at 0.40V(vs.Ag/AgCl) appeared when the potential was scanned forward positive.The height of the peak was linearly increased with the concentration of Pd(Ⅱ) over the range of 3 × 10-10- 1×10-7M.The detection limit was 1.2× 10-10M.The relative standard derivations were less than ± 7.5%.
