Abstract: Anew method for determination of trace germanium by adsorptive stripping catalytic voltammetry has been established.In a supporting electrolyte containing 1.5 × 10-3 mol/L DHB, 2.5 ×10-3 mol/L EDTAand 1 × 10-4 mol/L V(V), a sensitive adsorptive stripping catalytic peak of germanium-DHBcomplex was obtained by DPSat pH=2.1.The change of peak height with the concentration of germanium is linar in the range of 1.2× 10-10~8× 10-8 mol/L.

Key words: Germanium, Adsorptive stripping catalytic voltammetry
