Radiation crosslinking of chitin / chitosan derivatives such as carboxymethylchitin (CMCt) and carboxymethylchitosan (CMCts) has been investigated. CMCt and CMCts of 40% concentration were irradiated by electron beams. The maximum gel fraction of those CMCht and CMChts reached 72% (75kGy) and 50% (100kGy) respectively. These gels absorpted water of 8.3g for CMCt and 21.2g for CMCts per 1 g of the dried gel. The absorption ability of various metal ions with these gels has been investigated. The highest adsorption of scandium and gold has been obtained for CMCt and CMCts gels, respectively.
