摘要
从铜渣的碳酸铵-氨水浸取液中,用脂肪酸-正辛酸萃取铜,有机相用硫酸反萃取得到铜,水相用(NH4)2SO4-PEG-EBT体系萃取分离锌与镉,从而实现了铜、锌、镉的定量分离.
In virtue of fatty acids,copper is separated from distilling-liquid of copper-waste by using salvolatile-ammonia system,the organic-phase can be used to anti-extract to get copper with the sulfuric acid,the water-phase is extract to separate the zinc and cadmium with the ammonium sulphate-PEG-EBT system.Using these ways,the copper?zinc and cadmium can be separated quantitatively.
