提出了吸附溶出催化伏安法测定痕量锗的方法。该方法最佳体系为0.15 mol/L KCl+1.0×10~(-3) mol/L 3,4-二羟基苯甲醛(DHB)+2.0×10~(-3)mol/L EDTA+3.0×10~(-3)mol/L V(Ⅳ),pH2.15。其线性范围为1.2×10~(-10)～6.O×10~(-8)mol/L,最低检出浓度为3.6×10~(-11)mol/L Ge(Ⅳ)。
A method for the determination of trace germanium by catalytic stripping voltammetry was proposed. The optimal system was 0.15 mol / L KCl + 1.0 × 10 -3 mol / L DHB + 2.0 × 10 -3 mol / L EDTA + 3.0 × 10 ~ (-3) mol / LV (Ⅳ), pH2.15. The linear range was 1.2 × 10 ~ (-10) ~ 6.0 × 10 -8 mol / L, the lowest detection concentration was 3.6 × 10 ~ (-11) mol / L Ge (Ⅳ).
