| 摘 要： | 采用差分脉冲极谱法,在pH 1.50、含3,4 –二羟基苯甲醛(DHB)的H2SO4中,测得无机锗的峰电位为Ep=-0.54 V,Ge(Ⅳ)浓度在1.04×10 5～1.05×10 4 mol·L 1范围内与峰电流呈线性关系,利用该法用于测定蒙药那如三味丸中总锗、无机锗和有机锗,得到了满意的结果.

| Abstract: | The amount of Ge（ Ⅳ ） in pH 1.30 H2SO4 including 3,4 - dihydroxy benzaldehyde supporting electrolyte was determined by differential pulse polarography. The peak potential is located at Ep = - 0. 54 V with peak current proportional to concentration of Ge （ Ⅳ ） in 1.04 × 10^-5 - 1.05 × 10^-4 mol · L^-1 This method was applied to the determination of total germanium, organic germanium and inorganic germanium in Mongolia medicine Naru Sanwei pill with satisfactory results. |
