中文摘要:
      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。
英文摘要:
      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.
