摘要
本文建立了一种测定铜阳极泥中硒量的分析方法,对测定酸度,陈化时间等测定参数进行了优化,在6mol/L盐酸溶液中,用盐酸羟胺还原析出单体硒,过滤与其他大部分杂质分离,单体硒用酸溶解,用硫代硫酸钠标准溶液滴定。方法加标回收率为95.80%-101.3%,测定相对标准偏差（RSD）为0.049-1.40%。
A determination of copper anode slime analysis of selenium content is established,the parameters to test acidity and aging time etc.are optimized in this article.In 6mol/L hydrochloric acid solution,hydroxylamine hydrochloride is used to reductive selenium to separate from other impurities.Acid is used to dissolve selenium with sodium thiosulfate standard solution titration.The recovery percent is 95.80%～101.3%,RSD is 0.049～1.40%.
