摘要
试样经微波消解后,采用ICP-AES测定铜精矿中的硫含量。按本法所测铜精矿标准物质(GBW 07166)中硫含量,推荐值为33.8%±0.3%,6个平行样测定平均值为33.6%,测定结果的相对标准偏差RSD为0.318%。
The samples were treated by microwave digestion,and the content of sulfur in copper concentrate was determined by ICP-AES.The content of sulfur in the copper concentrate standard sample（GBW 07166） was measured by this method.The recommended value of the standard substance was 33.8±0.3%.The average of 6 duplicate samples was 33.6%,and the RSD was 0.318% for detection result.
