本文提出了(?)属—乙二胺—硫氰化钾—亚硫酸钠体系中联合测定微量锌、铜的新疗法.研究了方法的条件选择、波的极谱特性、干扰物及其影响、应用该法测定了滇池水、自来水、工厂污水及回收处理水中的锌、铜含量,与原子吸收分光光度法所得结果相符合,疗法简便、快速。灵敏度高,易于推广应用。 This paper presents a new therapies for the combined determination of trace zinc and copper in the system of (?) - ethylenediamine - potassium thiocyanate - sodium sulfite.The choice of conditions, the polarographic characteristics of wave, interferences and their effects are studied The method determines the contents of zinc and copper in Dianchi Lake water, tap water, factory effluent and recovery water, which is in accordance with the results obtained by atomic absorption spectrophotometry. The method is simple and rapid. High sensitivity, easy to promote the application.
