【摘要】:制定了分析氯化鉀鍍鋅溶液中氯化鋅的新方法。用氨配合鋅離子,加二甲基二硫代氨基甲酸鈉沉淀銅雜質(zhì),用三乙醇胺掩蔽鐵和鋁。在pH=10的條件下,以鉻黑T作指示劑,用EDTA標(biāo)準(zhǔn)溶液滴定氯化鋅。測定結(jié)果的相對平均偏差為0.11%,回收率為99.80%~100.16%。
[Abstract]:A new method for the analysis of zinc chloride in potassium chloride zinc plating solution was established. Copper impurity was precipitated by adding sodium dimethyl dithiocarbamate with ammonia and zinc ion, and Fe and Al were masked by triethanolamine. Under the condition of pH=10, zinc chloride was titrated with EDTA standard solution with chrome black T as indicator. The relative average deviation of the determination was 0.11 and the recovery was 99.80 and 100.16.
