Method for making high flux, high salt rejection cellulose desalting membranes |
| abstract |
A method is provided for producing a high flux, high salt rejection cellulose acetate desalination membrane. In this method, cellulose acetate polymer is dissolved in a first solvent such as methylene chloride or 2-methyltetrahydrofuran to produce a solution. Further steps involve stirring the solution, and thereafter permitting the solution to settle, for a time sufficient for a majority of the cellulose acetate to precipitate out of the solution to form a cellulose acetate precipitate. Next, the cellulose acetate precipitate is stirred into an excess methanol. Thereafter, the cellulose acetate is filtered out and used in making the desalination membrane. |
