摘　　要：采用差分脉冲扫描法,在pH=1.30H2SO4和3,4-二羟基苯甲醛(DHB)底液中,测得无机锗的脉冲极谱波,峰电位为Ep=-0.53V,Ge(Ⅳ)浓度在1.03×10-5～1.04×10-4mol·L-1范围内与峰电流呈线性关系,利用差分脉冲极谱法可以测得蒙药阿敏额尔敦中总锗、无机锗和有机锗含量,得到了满意的结果.<Abstrcat>Determination of Ge(Ⅳ)in pH 1.30 H_2SO_4 and 3,4-dihydroxy benzaidehyde supporting electrolyte by differential pulse polarography was developed.The peak potential at Ep=(-0.53) V,the peak current is proportional to concentration of Ge(Ⅳ)in 1.03×10^(-5)～1.04×10^(-4)mol·L^(-1).This method can be applied to determine the content of total germanium,organic germanium and inorganic germanium with satisfactory results.
