本文研究了钴(Ⅱ)-5-Br-PADAP体系的吸附伏安法。方法的线性范围为1×10~(-9)～5×10~(-7)mol/L。,检测下限为4×10~(-10)mol/L。并将此法应用于人发中痕量钴的测定。
In this paper, the adsorption of cobalt (Ⅱ) -5-Br-PADAP system voltammetry. The linear range of the method is 1 × 10 ~ (-9) ~ 5 × 10 ~ (-7) mol / L. , The detection limit of 4 × 10 ~ (-10) mol / L. This method was applied to the determination of trace cobalt in human hair.
