    • Object: This invention provides a method of refining an Rh-containing solution also containing at least one type of impurities of heavy metals, alkaline earth metals, and Ag.Means for solving the problems: The invention provides a method of refining an Rh-containing hydrochloric acid solution also containing Ag and at least one other impurity of heavy metals and alkaline earth metals, the method comprising the steps of: (a) adding an alkali to the solution to adjust pH of the solution to 7-12, whereby generating a neutralized precipitate containing Rh and other components; (b) filtrating and separating the neutralized precipitate; (c) adding a first hydrochloric acid for redissolving the neutralized precipitate in an amount such that the mole ratio of Cl to Rh (mole ratio Cl/Rh) of a resulting solution becomes 3-4; (d) filtering the resulting solution to remove Ag as precipitate, and (e) extracting the solution obtained by the previous step as an aqueous phase with DEHPA.
    • 发明内容本发明提供一种还含有至少一种重金属,碱土金属和Ag的杂质的含Rh溶液的方法。 解决问题的手段本发明提供了一种还含有Ag和至少一种其它杂质的重金属和碱土金属的含Rh盐酸溶液的方法,所述方法包括以下步骤:(a)加入碱 将溶液的pH调节至7-12,由此产生含有Rh和其它组分的中和沉淀物; (b)过滤并分离中和的沉淀物; (c)加入第一盐酸以使中和的沉淀物重新溶解,使得所得溶液的Cl与Rh的摩尔比(Cl / Rh的摩尔比)变为3-4; (d)过滤所得溶液以除去沉淀物,和(e)用DEHPA萃取由前述步骤获得的溶液作为水相。
