Outline of Final Research Achievements

Nano porous cellulose gel beads were successfully prepared by using an aqueous LiBr solution which is a new all-aqueous process of the dissolution / regeneration of cellulose. The prepared cellulose beads had high strength and specific surface area and were found to be useful as an adsorption / sustained release agent. Size exclusion chromatography using the cellulose beads showed a calibration curve close to a straight line against standard dextran. It was found that the cellulose gel beads prepared in this study have high performance as a support material for chromatography.
