【 摘 要 】

The need for clean water continues to increase. Therefore, it is necessary to find an alternative for the get of clean water. One way is desalination process using membrane. Cellulose Acetate/Polyethylene Glycol (CA / PEG) membrane is one type of membrane that can be used for desalination process. Several studies on the manufacture of CA / PEG membranes have been performed, but have not yet produced a good performance membrane. Therefore in this research was synthesize CA/PEG/mixing solvent membrane using Acetone - THF/Acetone - DMF as the solvents at ratio 100-0, 90-10, 70-30, 50-50 (%volume) each and PEG as the additive vary PEG 200 and 400. CA/PEG/mixing solvent membrane characteristics are tested. The results showed that the hydrophilicity of mixing solvent method using Acetone-DMF (50:50) increase water content up to 375.86% and Acetone-THF (50:50)'s water content increase up to 177.10% with additive PEG 200, and for PEG 400 as additive showed that the hydrophilicity of mixing solvent method using Acetone-DMF (50:50) increase water content up to 503,86% and Acetone-THF (50:50)'s water content decrease from 173,28 % till 119,23%, as THF content increase.
