摘要
提出在0.12 mol/L HCl-0.004 g/L连苯三酚-0.000 02 g/L偏钒酸铵的混合底液中,用二次导数,阴极化扫描示波极谱法测定微量锗。Ep约-0.68 V。在0~1 μg/10 mL时Ip与浓度线性良好,检出下限可达4 ng/mL。本文采用在9.6 mol/L HCl中用苯萃取锗的方法分离获得满意结果。
This paper reports the determination of trace germanium by oscillopolarographic in the mixture solution of 0.12 mol·L-1 HCl-0.004 g·L-1 1,2,3-Benzontrail-0.00002 g·L-1 Ammonium metavanadate.The peak potential is about 0.68 v(vs·SLE).In the range of 0~1μg·(10ml)-1 for the concetration of germanium,Ip Linear is good,and the detecting lower limit attains 0.04 μg·(10ml)-1 the result of isolating germanium from 9.6 mol·L-1 HCl by extration is satisfaetory.
