摘要 利用N205-N1923-煤油液膜体系,CaCl2溶液作内相,对高氟废水的处理进行了研究.利用正交实验确定了影响最大的因素,并研究了各种因素对处理的影响.经30min处理,外相F-浓度可由0.500g/L降至0.010g/L以下,可达到工业排放标准. The treatment of wastewater containing high concentration of F - with emulsion liquid membrane is described. The liquid membrane consists of water in oil emulsions where the oil phase comprises polyamine N 205 as surfactant, primary amine N 1923 as carrier, kerosene as solvent, and the internal phase comprises CaCl 2.The concentration of F - in external phase was reduced from 0.500 g/L to an average of 0.010 g/L which has reached the draining standard in our country.
