摘要
研究了用 (NH4) 2 SO4存在下氯化亚锡—丙醇体系萃取分离铂 (Ⅱ )的行为及体系在盐酸介质中的分相条件 .实验表明在盐酸介质中体系可萃取铂 (Ⅱ ) ,其萃取率为 99.4 % ,该方法可用于从贱金属中分离铂 (Ⅱ ) .
A new method for separation of platinum (Ⅱ)by liquid-liquid extraction system of stannous chloride - n-propyl alcohol by ammonium sulfate has been investigated. The experiment results indicate that the extraction ratio of Pt(Ⅱ)is 99.4%in hydrochloric acid medium. The proposed method can separate Pt from Fe,Al,Zn,Ca etc.base metals.
