摘    要:合铜物料(铜矿石、铜精矿、铜锍等)经混合酸溶解后,在10%HCl介质中,采用新型巯基棉分离富集-电感耦合等离子体原子发射光谱法测定Au,Ag。对巯基棉制备方法、溶样条件、分离富集条件、共存元素及基体干扰等进行了实验,结果表明,含铜物料中常见的12种共存元素对该方法测定金、银不产生干扰,方法基体效应较小,各待测元素之间也没有明显干扰。在最佳仪器工作条件下,方法的回收率为97.0%~103.0%,相对标准偏差RSD(n=12)为0.75%-1.95%。采用该方法分析测定标准物质和不同产地的实际样品,分析结果与推荐值和其他常规方法测定值一致,均在允许误差范围内。该方法与现行的单元素分析测定方法相比,简便快速,结果可靠,适用于大批量含铜物料进出口检验。

关 键 词:巯基棉      含铜物料  电感耦合等离子体原子发射光谱法

Abstract:First,copper-containing materials(copper ore,copper concentrate,copper matte etc.) are dissolved with mixed acids.And then,gold and silver are separated and enriched by sulfhydryl cotton fiber(SCF) in 10% HCl solution.Then gold and silver are determined with inductively coupled plasma-atomic emission spectrometric.The preparation of SCF,the sample slaking conditions,the separating and enriching conditions and the interference between matrix and concurrent elements are discussed.Twelve concurrent elements ha...
Keywords:sulfhydryl cotton fiber (SCF)  element determination  gold  silver  copper-containing materials  induetively coupled plasma-atomic emission spectrometry
