摘要
为了防止含氟废水的污染,人们研究了多种除氟方法,液膜技术是一项新的分离工艺,它操作简单,试剂用量少,有机相可重复利用。本文利用伯胺作迁移载体处理高含量的含氟废水,分离效率较好。 伯胺N_(1923)(简写RNH_2)为流动载体,上胺N_(205)(上海石油化工厂)为表面活性剂,煤油为溶剂。将内相CaCl_2,溶液与油相(含N_(1923)、N_(205)和煤油)按一定体积比例混合,高速搅拌。
The treatment of fluoride waste with emulsion liquid membrane is described. The liquid membrane consists of water-in-oil emulsions where polyamine N-205 was used as surfactant, primary amine N_(1923) as carrier, kerosene as solvent, and the internal phase was CaCl_2 solution. The concentration of F^- was reduced from O. 500g/L to an average of 0.010g/L after treatment.
