摘要: 研究了大孔膦酸树脂对毒砂中主、次和痕量元素的吸附行为及洗脱条件,结合巯基棉和TBP柱分离技术,建立了两个分离流程。在J-A1160型多道直读光谱仪上实现了毒砂单矿物中包括主量元素Fe和As在内的20个元素测定。主量元素As和Fe的相对标准偏差(n为5～10)分别为1.03％和0.9％,其它元素在5％～11％范围。流程经实际试样分析验证,结果与化学法相符。Abstract: In this paper, two schemes were established for the analysis of arsenopy-rite by ICP-AES.In the first scheme, macroporous phosphoric acid resin was used for the separation of large amounts of iron from the arsenopyrite sample solution. The sorption and de
