壳聚糖固载环糊精吸附剂的研究进展

环糊精(CD)具有"内疏水,外亲水"的特殊分子结构,可作为"宿主"包络不同"客体"化合物,形成结构特殊的包络物的能力。壳聚糖及其衍生物具有较强的吸附能力,其经不同方法固载化环糊精以后,具有壳聚糖的吸附功能和CD的包结双重特性,具有更强的吸附能力。其作为吸附剂可吸附胆固醇、苯酚类物质、色素和控制缓释,广泛应用于医药、环保等领域。对壳聚糖衍生物固载环糊精的固载方式、性能、应用等进行了阐述。

Progress of research on the chitosan bearing cyclodextrin adsorbent

Cyclodextrin(CD) has the merit of a hydrophobic cavity,which is easy to assemble with other molecules.Chitosan and its derivatives has the merit of powerful absorbability.Therefore,the products obtained by CD grafting to chitosan using different methods have the properties of sorption of chitosan and inclusion ability of CD,and have a more powerful absorbability.They can absorb the cholesterin,phenol,dyes and controll release as adsorbent,are widely used in medicine,environmental protection and so on.In this review,various kinds of strategies involved in the grafting of CDs onto chitosan are discussed in detail.In addition,the inclusion ability and the properties of CD grafted chitosan derivatives and their applications are also discussed.
