Ab initio calculation of the structure of acetate cellulose membranes for reverse osmosis
- 44 Downloads
The elementary unit of the monoacetate cellulose membrane in lithium, sodium, and potassium chloride solutions was simulated with the Gaussian-98 program package. The results are used for qualitative explanation of the selective transport of water in comparison with electrolyte in the case of reverse osmosis.
