清液萃取
liquid-liquid extraction
q ingye CUIqU清液萃取(liquid一liquid extraetion)以不含固体悬浮物为水相料液的溶荆苹取方法。料液中的固体粒子在萃取过程中常常会产生乳化，在相界面形成污垢，影响分相。因此，含固体粒子的料液在进入萃取作业之前一般都要经过过滤或澄清处理，以除去料液中的固体粒子。当今的溶剂萃取主要采用清液萃取。 清液萃取的应用很广泛，工业上用溶剂萃取法分离或富集重有色金属如铜、镍、钻等，稀有高熔点金属如错、铅、妮、钮、钨、铝、钒、钦等，轻金属如铝、镁、银等，稀有轻金属如被、锉、枷、艳等，稀散金属，卜，、州、钳、锗、锌、硒、蹄等，贵金属如金、银、铂、把、铭、饿、铱、钉，铀、社及稀土都是采用清液萃取。在有机化学工业及分析化学中也都使用清液萃取。
