摘要
用5-Br-DMPAP作显色剂,表面活性剂CTMAB作增溶剂,采用分光光度法测定微量锗。结果表明:方法的线性范围为:2.5~25.0μg/25mL,表现摩尔吸光系数为7.97×104L.cm-1.mol-1,变异系数为3.5%,回收率为99.6%。
A method to detect the content of Micro-rhodium by spectrophotometrymethod is studied.5-Br-DMPAP is a reagent,CTMAB is a surface acthre agent.The results show that working range is 2. 5~25.0ug/25ml, Molar absorptivity is 7. 97 ×104L.cm -1. mol-1,R. S. D is 3. 5%,recovery is 99. 6%.
