四环素体系分光光度法测定电镀液中钐的研究
Study on Determination of Samarium in Electroplating Solution by Spectrophotometry with Tetracycline System
Abstract
提出在弱碱性介质中对钐-四环素体系采用分光光度法测定钐的方法，测定波长为404nM.本方法具有较好的选择性和灵敏度，方法的回收率为97.1%~103.8%，检出下限为3.93x10-8g/Ml. A spectrophotometric method is used to determine the contents of samarium in an electroplating solution, with tetracycline as the complex reagent.The contents of samarium is related to the absorption value at 404 nm.This method is simple, convenient and accurate.It can be used in the determination of samarium in an electroplating solution.The detective limit is 3.93×10 -8 g/mL and the recoveries are from 97.1 % to 103.8 %.
