The nonporous homogeneous cellulose membrane for forward osmosis was prepared via phase inversion method using ionic liquid 1-ethyl-3-methyl-imidazolium acetate (EMIMAc) as solvent, water as nonsolvent on a non-woven fabric substrate. The characterizations of Fourier transform infrared (FTIR) and X-ray diffraction (XRD) spectroscopies showed that no obvious change occurred in the chemical structure of cellulose after membrane formation, but the crystallinity had a certain degree of decline. The cross-section and the surface morphologies of the cellulose forward osmosis membrane were analyzed by scanning electron microscopy (SEM). The membrane performance were investigated by measuring water flux and rejection of simulated seawater. The water flux of the cellulose forward osmosis membrane, which the cellulose concentration is 8 %(wt) in casting solution, was 3.534 L/m₂.h and the rejection for NaCl was more than 99 %, using 0.6 mol/L NaCl solution as the feed solution and lab-made nutrient solution as the draw solution.
