Figure 4. (a) Adsorption-desorption isotherms of N2 at -196°C of 80°C-outgassed (empty squares) chitosan, (filled trangles) zeolite X-chitosan composite from in-situ zeolite synthesis and (empty triangles) zeolite Y-chitosan composite from encapsulation of the zeolite in the gelling chitosan. (b) Scanning electron micrographs of a calcined zeolite-chitosan bead prepared by zeolitisation of a silica-chitosan composite. 

Removal of about half of the linear polymer by solvent extraction left individual zeolite crystals containing the remaining polymer. Scanning electron micrographs showed there was essentially no polymer between or on the zeolite (observable before the extraction), and resembled micrographs of the pure zeolite. All linear polymer could be removed on extended solvent extraction.
