摘　　要：为实现中控液体物料中金、钯、铂元素的精准定量分析,为工艺生产定向富集和高效提取提供数据支持,建立了电感耦合等离子体原子发射光谱(ICP-AES)法测定中控冶炼系统中高镍铜液体样品中金、铂和钯3种元素含量的测定方法。确定了试液用碲共沉淀,贵金属进入滤渣,经火试金分离富集得到贵金属合粒,合粒经王水溶解后,于王水介质中在电感耦合等离子体原子光谱仪上同时测定金钯铂的量。金、铂、钯的测定范围为0.014~5 mg/L,加标回收率为92.2%~104%,相对标准偏差(RSD)为3.2%~10.6%,方法满足高镍、铜液体样品中金、钯、铂元素的测定要求。In order to improve the accurate quantitative analysis of gold,palladium and platinum in central control liquid materials,and provide data support for directional enrichment and efficient extraction in process production,a method for the determination of gold,platinum and palladium in high nickel-copper liquid samples in smelting systems using ICP-AES was established.It is confirmed that the element of Au,Pd and Pt in test solution could be co-precipitated by tellurium,and the noble metals was enriched in the filter residue.After separation and enrichment by fire assaying,the composite particles were obtained,and then it was dissolved by aqua regia,the gold,palladium and platinum in prepared solutions was simultaneously detected by on ICP-AES.The linear range of gold,platinum and palladium is 0.014—5 mg/L,the recovery is 92.2%—104%,and RSD is 3.2%—10.6%.The method is suitable for the determination of gold,palladium and platinum elements in high nickel and copper liquid samples.
