摘要
提出了一个快速分离与测定大量铜中微量钽的新方法。采用铁氰化钾-亚铁氰化钾沉淀铜基体使微量钽分离,并用分光光度法测定了微量钽。方法快速简便,分离效果很好。
A new method for rapid separation and determination of trace tantalum in copper mass is presented.The copper matrix is separated from tantalum by precipitation with K_3[Fe(CN)_6]·3 H_2O and the trace tantalum in copper mass is determined by spectrophotometry.In addition to good separation results,this method has the advantages of rapid,simple and convenient.
