Abstract: 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 N1923 as carrier, kerosene as solvent, and the internal phase was CaCl2 solution. The concentration of F- was reduced from O.500g/L to an average of 0.010g/L after treatment.
