最近用液膜来分离金属离子、络合物、有机物的研究活跃起来了。特别在湿法冶金及废水处理方面已进入工业化阶段。液膜是黎念之于1968年发明的。后来他又进行了系统的研究,70年代初期,E.L.Cissler等人仿照生物膜中的物质特殊传输现象,制成了含有载体的仿生膜。从此,从稀溶液中浓缩分离离子变为可能。十多年来由于黎氏等人的努力,在湿法冶金、废水处理、烃分离、医药、农业及其它领域进行了广泛的研究,取得了较大的突破,有的已进行了中间工厂生产试验,取得较好的效果,受到了人们的重视。近几年来我国也有些单位先后开展了工作,并已取得了一些成果。 Recent studies on the separation of metal ions, complexes, and organic matter by liquid membranes have been active. Especially in hydrometallurgy and wastewater treatment has entered the stage of industrialization. Li Nian was invented in 1968. Later, he conducted a systematic study. In the early 1970s, E.L. Cissler and others modeled on the phenomenon of special transport of substances in the biofilm to produce a biomimetic membrane containing a carrier. Since then, it has become possible to concentrate and separate ions from dilute solutions. For more than a decade, due to the efforts of Li et al., Extensive research has been carried out in the fields of hydrometallurgy, wastewater treatment, hydrocarbon separation, medicine, agriculture and other fields, and great breakthroughs have been made. Some have carried out intermediate plant production Experiments, achieved good results, has been the people’s attention. In recent years, some units in our country have successively carried out their work and have achieved some results.
