Principle and current status of nickel-containing effluent treatment using emulsion liquid membrane

Emulsion Liquid Membrane (ELM) technology is an effective method in solution recovery and effluent disposal for its high efficiency, fastness, and selectivity. Several methods of disposing nickel containing effluent were presented. The principle and process of ELM technology to dispose nickel containing effluent were described. Selection of surfactant, fluid carrier, in water phase and membrane solvent in EML technology was discussed. The optimal process factors including pH value, ratio of oil to water, agitating rate, working time and complexation effect were determined. In addition, the developing trend of ELM technology to dispose nickel containing effluent was presented.
