我们已介绍了用负载螯合剂阴离子交换膜测定微量铀的可能性。本文介绍用锌试剂作为负载螯合剂的阴离子交换膜测定微量铜的可能性。实际样品的测定结果与用碘量法和原子吸收光度法测定的结果一致。实验部分一、试剂与仪器 1.锌试剂(北京化工厂产品):0.1％水溶液。 2.缓冲液:pH1～2是盐酸-氯化钾体系,pH3～8是邻苯二甲酸氢钾-氢氧化钠体 We have described the possibility of measuring trace amounts of uranium with a chelating anion exchange membrane. This article describes the possibility of using a zinc reagent as a chelating agent-loaded anion exchange membrane for the determination of trace amounts of copper. The actual results of the determination of the sample with iodometry and atomic absorption spectrophotometry consistent with the results. Experimental part A, reagents and instruments 1. Zinc reagent (Beijing Chemical Plant products): 0.1% aqueous solution. 2. Buffer: pH1 ~ 2 is hydrochloric acid - potassium chloride system, pH3 ~ 8 is potassium hydrogen phthalate - sodium hydroxide
