壳聚糖作为分离膜材料的研究进展

Advances in Chitosan Membranes

介绍了甲壳素和壳聚糖的制备、结构和性质,对壳聚糖在反渗透膜、渗透蒸发膜、超滤膜、纳滤膜、亲和膜、离子交换膜、气体分离膜等方面的应用进行了综述。

Chitin is a kind of uniform polysaccharide containing attunes, It can be used in biosynthesis and is also biodegradable, so its use will not pollute environment. Chitosan is the product of chitin deacetytation. Chitin and chitosan are promising membrane materials because of their good chemical reactivity and film- forming property. The preparation, structure and characteristics of chitin and chitosan are described. They have been used as membrane materials for reverse osmosis, pervaporation, ultrafiltration, nanofiltration, affinity, ion exchange and gas separation. Their preparations and applications are reviewed in detail.
