摘要
本文详细地研究了在 HCl介质中 ,巯基棉分离富集 Au、Ag,KIO3- HCl解脱 Au,原子吸收分光光度法测定金、银的方法。本方法一次溶样连续测定 Au、Ag,简便快速 ,分析结果可靠。在 Au32 μg、Ag40 0 μg范围内 ,Au回收率 98.8%— 1 0 1 .2 % ,RSD为 3% ;Ag回收率 97.3%— 1 0 1 .3% ,RSD为 2 %。
In this paper,the method of determining silver and gold by FAAS in conditions of separating enrich Au,Ag with SNF in HCl medium and disengagement of gold with KIO 3 HCl has been investigated.Silver and gold are determined continuously by once dissolve sample.This method is simple and rapid.The result is credible.In range of 32μg gold and 400μg silver,the recovery of gold and silver was 98.8% —101.2% and 97.3%—101.3% respectively.The RSD of gold and silver was 3%(Au) and 2%(Ag),respectively.
