This paper examines the application of supported liquid membrane for the removal of organic compounds in the aqueous waste effluents. Polypropylene glycol was employed as carrier mounted on PTFE supports. It has been demonstrated that polyols act as efficient carrier for selective removal of organic compounds having an acidic -OH group. Mass transfer coefficient in creased when the number of carbon atoms in creased from 4 to 6. A correlation between pKa, pH and flux of permeating species has been demonstrated. Aromatic compounds showed higher transportrates as compared to similar aliphatic compounds. Effect of temperature on the transportrates has been studied. It has been shown that a mock waste solution can be transported up to >90% under the conditions studied.
