摘要
本文研究了KSCN存在的条件下双 (正 -辛基亚磺酰 )乙烷 (简称BOSE) -乙酸丁酯体系萃取Pd、Pt的行为。实验结果表明 ,利用 1～ 2mol/LHCl介质可以进行Pd、Pt的定量分离。本法应用于合成矿样的Pd、Pt分离富集 。
The extracting behavior of palladium and platinum by bis(n-octylsulphinyl)ethane(BOSE)/butylacetate extraction system from hydrochloric acid medium in the presence of KSCN was studied.Experimental results showed in the range of acidity from 1～2 mol/L HCl,platinum was extracted less than 3%,but palladium can be extracted quantitatively.So this system can separate Pd(Ⅱ)-Pt(Ⅳ).General base metals and noble metals do not disturb the process.The method has the advantages of high selectivity.It has been applied to the separation and determination of Pd(Ⅱ)-Pt(Ⅳ) in synthetic ores.
