Abstract
⺠The chitin hydrogels were successfully prepared from chitin solution in 8 wt% NaOH/4 wt% urea aqueous system by crosslinking with 5 wt% epichlorohydrin. ⺠The chitin hydrogels exhibited high efficiency to remove dye (malachite green) from aqueous solution, as a result of their microporous structure, large surface area and affinity on the dye. ⺠The activation energy calculated from Arrhenius equation and the result of SEM and FTIR indicated that the adsorption of malachite green on the chitin hydrogels was physical process.
