火试金富集-电感耦合等离子体发射光谱(ICP-OES)法测定分银渣中的铂、钯
|
摘要
采用火试金富集得到贵金属合粒,经王水溶解,在王水(10%)介质下采用全谱直读电感耦合等离子体发射光谱(ICP-OES)法测定分银渣中铂、钯的含量。方法精密度好,准确度高,铂、钯的加标回收率在98.4%~102%,可以很好地满足分银渣中铂、钯含量的测定。
Sub-silver residue is the main by-product of copper anode mud electrolysis which contains a measureable amount of noble metals of platinum and palladium.In this study,a method based on ICP-OES was described for rapid and accurate determination of platinum and palladium content in sub-silver samples.Fire assay preconcentration was used to obtain composite granule which were dissolved in 10%aqua-regia for sample preparation.The described method showed good precision and high accuracy with recovery rate ranged from 98.4%to 102%,and can be widely utilized for platinum and palladium content measurement in sub-silver residue.
