Abstract：

Cellulose triacetate forward osmosis membrane was prepared by phase inversion method. The polymer solution consisted of cellulose triacetate as the membrane material, 1, 4-dioxane and acetone as solvent, and lactic acid as additives. The effects of support materials, solvent evaporation time and the additive content on the membrane performance were investigated. 0.1mol/L NaCl was used as the feed solution and 4mol/L glucose was used as the draw solution. The water flux was between 6 and 7 L / (m2h) and the rejection for NaCl was above 95% .
