中文摘要: 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,本文建立了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光谱仪上同时测定金钯铂的量。该方法金、铂、钯的测定范围为 0.014mg/L~5mg/L,回收率为92.2%~104.4%, RSD为3.21%~10.58%,方法满足高镍、铜液体样品中金、钯、铂元素的测定。

Abstract:In order to realize 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. This paper studies and establishes an ICP-AES method for the determination of gold, platinum and palladium in high nickel-copper liquid samples in smelting systems. Through the experiment, it is confirmed that the test solution is co-precipitated with tellurium, and the precious metal enters the filter residue. After separation and enrichment by the fire test Gold, the composite particles are obtained, and after dissolution by aqua regia, simultaneous determination of the amount of gold, palladium and platinum on an inductance coupled plasma spectrometer in aqua regia medium. The determination range of gold, platinum and palladium is determined to be 0.014mg/L ~ 5mg/L, the recovery rate is 92.2%~104.4, RSD is 3.21%~10.58%. The method is suitable for the determination of gold, palladium and platinum elements in high nickel and copper liquid samples.
