| Abstract: | The extraction of citric acid by supported liquid membrane was investigated.The effects of membrane assembly methods and carrier concentration on transfer flux and membrane stability were discussed.The experimental results show that the suitable composition of the supported liquid membrane system under the given operoting conditions are:polypropylene porous membrane as the support,95% kerosene as the solvent and 5% tri-n-octyl amine(TOA) as the carrier. |

| Keywords: | supported liquid membrane citric acid carrier facilitated transport |
