摘要
纯锌样品经酸溶解后在6mol/L的HCl中用次亚磷酸钠将Te(Ⅳ)还原为单质Te,与锌基体及其它杂质分离后,在氨性酒石酸钾钠-Pb-EDTA溶液中进行极谱测定。该方法的检出限为2×10-3μg/mL,平均相对偏差不大于5%。
The pure zinc samples were dissolved in acid after 6mol / L of HCl using sodium hypophosphite to Te(Ⅳ) reduced to elemental Te,and Zn and other impurities in the matrix after the separation of potassium sodium tartrate in the ammonia-Pb-EDTA solution for polarography.The detection limit is 2×10-3μg/mL,the relative average deviation is less than 5%.
