| 摘 要： | 在1,8M H2SO4-0.5M NaBr-2.9×10-4M TPAC支持电解质溶液中,镉(Ⅱ)-NaBr-TPAC产生一个尖锐灵敏的吸附还原波,其峰电位为-0.71V(vs.SCE)。镉浓度在 7.1×10-8—8.5×10-8M范围内与峰高呈线性关系,检测下限为7.1×10-8M。本文用2.5次微分电分析法对底液条件进行选择,对极谱波的性质进行了初步探讨,并用本方法测定了铝合金和电镀工业废水中微量镉的含量,结果较满意。

| Abstract: | In the supporting electrolytes solution of 1.8M H2SO4-0.5M NaBr-2.9×10-4M TPAC, Cd-NaBr-TPAC produces a sharp sensitive polarographic adsorptive wave. Its peak potential appears at-0.71V(vs. SeE), and its peak height bears a linear relationship to the con |
