摘要
提出了高分子胺纤维交换柱快速分离铜基体 ,同时富集铋的新方法。用硫脲洗脱 ,同时显色 ,成功的测定了铜电解液中微量铋。用本方法测定铜电解液中 0 0 0 0 39g/L铋 ,相对标准偏差为 3 2 4% ,检出限为 0 0 0 0 38mg/L。
A spectrophotometric method for the determination of bismuth in the electrolytic solution of copper with thiourea after separation concentration by a column filled with fibre of high molecular amine has been developed. The detection limit of the method for bismuth is 0 00038mg/L and its precision is 3 24%(RSD) The method is rapid It has been used in the quality control of the electrolyte in the factory with great success
