【摘要】 研究了多孔壳聚糖膜对乙醇-水混合体系中微量醛的吸附性能。通过对影响其吸附性能的各种因素如壳聚糖膜的制备方法、用量、醇-水体系中醇浓度、酸度及其温度等的研究，认为壳聚糖适用于醇-水混合体系中微量醛的清除，并据此提出了吸附操作的优化条件。更多还原

【Abstract】 Porous chitosan membranes were prepared and their adsorption properties for aldehyde were investigated. The effects of alcohol concentration, crosslinking degree of membranes, temperature, and acidity were conducted. The experimental results showed that aldehyde could be adsorbed on chitosan membranes.更多还原
