Determination of Hazardous Elements in Smelter-Produced Sulfuric Acid.

摘要

The report presents results of analyses of potentially hazardous impurities (trace elements) in sulfuric acid produced by non-ferrous smelters. Sulfuric acid samples were obtained from acid plants attached to copper,lead,and zinc smelters. Results of analyses provided by some smelters are also included. Trace elements subjected to qualitative and quantitative determinations in this study include:Pb,Cu,Zn,Hg,As,Cd,Se,Sb,and Be,as well as other elements detected in significant concentrations during screening tests. Based on this analytical data,the report indicates yearly outputs of hazardous trace elements contained in smelter-produced acid for possible consumption in a variety of industries. The report also presents information on analytical methods and procedures used in acquiring the reported data.
