| 摘 要： | 介绍了钼精矿及烟道灰中铼的酸溶-萃取光度测定法。对溶样、萃取分离、显色、测定等条件进行了系统的试验研究，确定了铼的最佳测定条件。运用此法进行钼精矿及烟道灰中铼的测定，相对标准偏差 (n=11)均小于3.5%。经与其他实验室不同分析方法 (ICP-AES标准加入法、碱熔-萃取光度法)进行数据比对，结果令人满意

| Abstract: | The acid decomposition-extraction-spectrophotometric method of determining the rhenium concentration in molybdenum ores and flue dust was introduced. The conditions such as dissolution methods, extraction, absorption curve and determination were investigated systematically. The optimal condition of rhenium measurement was obtained based on a series of tests. The concentration of rhenium in different molybdenum ores and flue dust was determined by the proposed method; the relative standard deviation (RSD) of the method is below 3.5 %. Compared with ICP-AES standard addition method and alkaline fusion-extraction spectrophotometric method, the method gets satisfying results |
