摘要：

Glucosamine was directly intercalated into gamma-zirconium phosphate (gamma-ZrP). The intercalation compound with a monolayer structure was obtained by the interaction between the 2-amino group of glucopyranose and the phosphate group in gamma-ZrP. The uptake amount depended on the concentration of the glucosamine aqueous solution rather than reaction time, and reached 0.9mmol per gram of gamma-ZrP at the maximum. On the other hand, chitosan, polysaccharide of glucosamine, could be intercalated into alkylamine-interealated gamma-ZrP as the host compound. Chitosan-intercalated gamma-ZrP showed two phases with different interlayer distances. It was confirmed from C-13 CP/MAS NMR spectra that chitosan exists in the interlayer region of gamma-ZrP for both phases.
