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.
