Determination of Sulfur in Copper Concentrate by ICP-AES

Hai Li

Abstract

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.
