%X Triolein is successfully embedded into cellulose acetate (CA) by phase inversion. This prepared flat membrane can effectively remove trace lipophilic organic pollutants from water. Structure of hybrid membrane is mainly observed by scanning electron microscope (SEM). Triolein dispersion by mechanical rabbling and ultrasound are investigated. Ultrasound can more effectively strengthen triolein dispersion than mechanical rabbling. Effect of casting membrane temperature (room temperature, 0 degrees C) shows low temperature can help to forming smaller triolein droplets. In addition, interaction between triolein and CA belongs to physical mixing by the observation of FT-IR, accordingly triolein structure is not changed and adsorptive capacity for persistent organic pollutants is not affected. Triolein in hexane is analyzed by fluorometric measure. The results show that triolein is completely embedded into membrane, so it is impossible that triolein leaks into water in the process of the adsorption.
