研究了壳聚糖（ＣＳ）与醋酸纤维素（ＣＡ）渗透汽化共混膜的制膜条件，测定了该膜对乙醇－水混合液的渗透汽化性能及平衡溶解吸附性能实验表明，壳聚糖－醋酸纤维素共混膜对乙醇质量分数为５０％～９５％的乙醇－水溶液具有良好的渗透汽化分离性能
The film formation conditions of the pervaporation blend membrane of chitosan (CS) and cellulose acetate (CA) were studied. The pervaporation performance and equilibrium solubility and adsorption performance of the membrane on the ethanol - water mixture were determined. The sugar-cellulose acetate blend membrane has good pervaporation separation performance for ethanol-water solution with ethanol content of 50% -95%
