摘要
本文提出测定纯铜中锌的快速分析方法。在1.2N盐酸介质中用高分子胺萃取,硝酸钾-碘化钾混合液反萃取后硫氰酸盐-结晶紫光度法测定锌。可在25分钟内完成一个试样分析。
A rapid analysis method for determining the content of Zn in pure copper is given in this paper. Samples in 1.2N hydrochloric acid are extracted with macromolecular amine and reversely extracted with KNO_3-KI mixed solution. The amount of Zn is then can be determined with thiocyanate crystal UV spectroscopy. The analysis of a sample can be accomplished in 25 minutes.
