二—(2—乙基己基)磷酸(P204)是一种良好的萃取剂,已广泛地被应用于稀土和有色金属的萃取分离,这方面的研究工作国内外都有报导但用P204在石蜡相中对铜(Ⅱ)萃取的研究未见报导。本文指在探索在以石蜡为溶剂的体系中P204对铜(Ⅱ)的萃取机理,即用常温下为固态的石蜡加热
Di-2- (2-ethylhexyl) phosphoric acid (P204) is a good extractant and has been widely used in the extraction and separation of rare earth and non-ferrous metals. Studies in this area have been reported both at home and abroad. However, Phase on the copper (Ⅱ) extraction of the study has not been reported. This article refers to the exploration of the extraction mechanism of copper (II) by P204 in a paraffin-solvent system, that is, paraffin wax is heated at room temperature in a solid state
