The Preparation and Properties of Styrene Grafted Cellulose Acetate Membranes for Desalination
Membranes formed from secondary cellulose acetate have been the most successful for the reverse osmosis method of desalination. However, the high pressures used for seawater desalination lead to the gradual compaction of the expanded Loeb-Sourirajan type membrane structures with a consequent decrease of the product flux rate and apparent salt rejection. It seemed of interest, therefore, to study modifications of cellulose acetate which would reduce the rate of compressive creep of the modified membrane and, in turn, stabilize the flux-rejection characteristics of the resulting membranes.
