摘    要:使用萃取光度法对钼精矿浸出液中的铼进行测定,对萃取、显色及测定过程进行了试验,优化了掩蔽剂用量、萃取次数、萃取时间、pH、水浴温度及还原剂用量等条件。结果表明:在波长426nm处,铼在2~30μg/mL浓度范围内与其吸光度呈良好的线性关系,RSD小于2.3%,检出限(3s/k)为0.08μg/mL,回收率在91.2%~103.4.8%之间,与ICP-AES标准加入法进行对比,结果一致。

Abstract:The extraction-spectrophotometric method was used to determine the rhenium in leaching solution of molybdenum ores. In the method, the extraction and deternination procedures were investigated and the experimental conditions were studied systematically. The results indicated that the linear regression equation of the method was A =0.01114C + 0.0229, the correlation coefficition was 0.9992, the precision (RSD%) was less than 2.3% and the recoveries were between 91.2% and 103.4%. The determination results were consistent with that of ICP method.
Keywords:leaching solution  potassium thiocyanate  rhenium
