- 摘要:
-
在PH为5~6的HAc-六次甲基四胺溶液中,Pb(Ⅱ)与铜铁试剂产生的络合物在单扫描示波极谱仪上可观察到一灵敏的导数极谱波,其峰电位为-0.64V(VS,SCE),峰电流与铅浓度在9.6×10-8~5.8×10-6mol·L-1范围内成线性关系,检测限为1.9×10-6mol·L-1,用以测定铅锌矿中铅的结果良好.同时研究了形成铅-铜铁试剂络合物吸附波的条件和性质,并用极谱法测定其络合比为1:1.

A complex of lead and cupferron, Pb (Ⅱ)-Cup, is formed in HAc-(CH2)6N4 solution at PH 56. It shows a senstive derivative wave on single sweep polarography, with a peak potential at-0. 64 V(VS.SCE). A linear relationship holds between the peak current and
