1引言 铊属高毒元素,且有积蓄性,列为优先监测的对象之一。在铊的分光光度分析法中,用得最普遍的是萃取光度法。大量使用有毒的有机溶剂将污染环境和损害健康。因此,水相胶束增溶分光光度法测定铭的研究日益增加。镉试剂及其衍生物作为铊的显色剂已有报道,但未见使用镉试
1 Introduction Thallium is a highly toxic element, and there is savings, as one of the priority monitoring targets. In thallium spectrophotometry, the most commonly used is the extraction spectrophotometry. Heavy use of toxic organic solvents can pollute the environment and damage health. Therefore, the study of aqueous micellar solubilization spectrophotometry Ming increasingly. Cadmium reagent and its derivatives as a developer of thallium have been reported, but no use of cadmium test
