【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．更多还原

【Abstract】 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.更多还原
