摘要
研究采用硫酸钡重量法测定银精矿中的硫量,通过条件试验确定方法的具体条件,该方法结果准确,重复性好,回收率为97.60%~103.24%,相对标准偏差小于1.3%,满足银精矿中硫量的测定要求。
This study used the barium sulfate gravimetry to determine sulphur content in silver concentrates,the specific conditions of the method are determined through conditional tests. The method is accurate and reproducible,the rate of recovery is 97.60%~103.24%, and the relative standard deviation is less than 1.3%. Meet the requirements for determination of sulphur content in silver concentrate.
