摘要
应用了Ge(Ⅳ)在没食子酸-V(Ⅳ)-EDTA体系中的极谱波。其峰电位为-0.60V,线性范围为5×10-8～2×10-6g/L,检测限为4×10-9g/L。方法无需预处理直接用于Zn电解中微量Ge的测定,结果满意。
An oscillopolarographic method for the rapid determination of trace germanium in the medium of gallic acid-V(Ⅳ)-EDTA was presented.The peak potential was at-0.60 V,the linear range of the determination was 5×10^(-8)～2×10^(-6) g/L,and the detection limit was 4×10^(-9) g/L.The method is directly used for the rapid determination of trace germanium in zinc electrolyte solution with satisfactory results.
