ICP-AES法测定离子交换法回收铼时含铼液中铼含量

摘要

离子交换法回收铼生产过程中产生的含铼液经过酸化处理后,采用ICP-AES法测定铼含量.对样品处理方法、分析谱线、背景干扰和基体干扰进行了考察.检出限为0.0029 mg/L,回收率为90%~103.6%.%Rhenium in liquid produced in the recovery of rhenium by ion exchange process was determined by ICP-AES.The processing methods, spectral lines, background interference and matrix interference were investigated. The detection limit of method was 0.002 9 mg/L.The recovery was 90%~103.6%.
