| 摘 要： | 在HCl-H3PO4介质中，铜与硫氰酸钾形成络合物吸附在滴汞电机上，在0．55V（VS．SCE）产生灵敏的络合物吸附催化波。铜在0．05～1．00mg·L-1范围内，其二阶导数峰高IPCu与浓度成正比。本方法可测定井水、矿泉水、自来水中微量Cu~(2+)。

| Abstract: | In the medium of HCl-H3PO4, complex compound of copper and potassium thiocyamate is formed being adsorbed at mercury electrode producing the acumivous complex adsorbed catalytic wave at- 0. 55 V. The second order derivative peak height is proportional to the concentration in the range of 0. 55~1.00 mg. L-1 for Cu2+ . This method can be used for the determination of Cu2+ in well water, mineral water and drinking water. |
