我省铜矿资源丰富,对于铜的分离以及工厂排出含铜废水的处理与回收,具有重要意义。用液膜技术分离铜的研究,国外已有较多的报导,并已取得较大的进展,发现能从矿井的大型铜萃取工厂产生的含铜废水浓集 Cu~(2+),这样不仅净化了水源,而且回收了铜。液膜分离的工艺一般采用的流动载体有 L1X—64(胺类化合物)、P204(2—乙基已基磷酸酯)、P17、P15、SME 529、KeLeX 100。膜溶剂有环已烷加聚丁二烯、矿物油、煤油、煤油加
Our province is rich in copper resources, which is of great significance to the separation of copper and the disposal and recovery of copper-containing wastewater discharged from the factory. The research on the separation of copper by the liquid film technology has been reported more and has made great progress abroad. It is found that the Cu 2+ -containing copper-containing wastewater generated from the large-scale copper extraction plant in the mine can not only concentrate Cu 2+ Purified water, but also recovered the copper. Liquid membrane separation process commonly used mobile carriers are L1X-64 (amine compounds), P204 (2-ethylhexyl phosphate), P17, P15, SME 529, KeLeX 100. Membrane solvent cyclohexane plus polybutadiene, mineral oil, kerosene, kerosene plus
