摘要
本文以四(4-三甲铵苯基)卟啉作显色剂,在阳离子表面活性剂CPB存在下的pH9.8缓冲溶液中,利用三阶导数分光光度法,对钴、镉、铅的同时测定进行了详细研究。本方法测定灵敏度较高,对合成样品进行测定,结果令人满意。
In this Paper, the derivative spectral behaviour of the reaction of cobalt, cadmium and lead with-meso tetra (4 trimethylammonium phenyl) porphine (T(4-TAP)P) has been studied in the presence of cetylpyridinium bromide (CPB). The third order derivative spectrophotometric method with high sensitivities has been developed for the simultaneous determination of the three component mixture.
