Effect of Chitosan Modification on its Structure and Specific Surface Area



Effect of Chitosan Modification on its Structure and Specific Surface Area

Krzysztof Barbusiński, Krzysztof Filipek, Szymon Salwiczek

The chapter shows various chitosan modification methods: preparation of hydrogel beads from powdered chitosan, cross-linking of beads using epichlorohydrin or glutaraldehyde and conditioning of beads using NaHSO4. For each modified and non-modified form of chitosan, the surface structure was analyzed using SEM images. Moreover, for chitosan and its modifications the specific surface area, the total pore volume and the total pore surface area were determined using BET nitrogen sorption isotherms.
