A study on separation and enrichment of p-aminophenol from aqueous solution with emulsion liquid membranes has been carried out. The effects of pH in internal aqueous phase

the concentration of the carrier and surfactant were examed. Under the optimal operation conditions

the experimental results show that the water treated attained the drainage standard when the concentration of p-aminophenol is 500mg8226;L-1

after dealing with two-stage liquid membrane process.
