SEPARATION AND ENRICHMENT OF p-AMINOPHENOL WITH EMULSION LIQUID MEMBRANES
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 500mg·L -1 , after dealing with two stage liquid membrane process
