Abstract
提出了利用二甲酚橙为显色剂测定电镀液中微量钞的一阶导数分光光度法.根据在624uM处的导数值测定钐的含量.本方法简单、快速、方便、准确,可用于电镀液中微量钐的测定.相对标准偏差小于3%,回收率为97.4%~101.8%.
 
First derivative spectrophotometric method For determining of micro samarium in electroplating solution is given,using xylenol orange as color reagent.The content ofsamarium is determined according to the derivative value at 624um.This method is simple,rapid,convenient and accurate.It can be used in the determination of micro samarium in electroplating solution.The relative standard deviations are less than 3% and the recoveries areFrom 97.4% to 101.8%.
