| 摘 要： | 提出了测定铜试剂的吸附阴极计时电位溶出法,其线性范围为1×10~(-8)—1×10~(-7)M,1×10~(-7)—5×10~(-7)M,检出限为5×10~(-9)M。测定灵敏度比文献值提高了两个数量级。与其它各种电化学分析方法比较,本方法最灵敏。结合循环伏安法也对其电极过程机理进行了探讨。

| Abstract: | The adsorptive cathodic chronopotential stripping method for the determination of sodium diethyl dithiocarbamate(SDDC) is put forward. SDDC can be measured in the concentration ranges from 1×10~(-8) to 1×10~(-7)M, and from 1×10~(-7) to 5×10~(-7)M, and the detection limit is 5×10~(-9)M. It is the most sensitive of all the electroanalytical methods. At the same time, the electrode process is investigated with cyclic voltammetry. |
