논문 초록 (Abstract)
A new type of chitosan hydrogel beads (CSB) with a core-shell membrane structure was generated by sodium dodecyl sulfate (SOS) gelation process. CSB exhibited higher mechanical strength and acid stabi lity than chitosan hydrogel beads (CB) formed by alkali gelation. The effect of SDS concentration variation during gelation on the adsorption capacity of CSB for congored (CR) as a model anionic dye showed that CSB formed by 4 g l(-1) SDS gelation had the highest adsorption capacity.The maximum adsorption capacity of CSB (208.3 mg g(-1 )) obtained from the Sips model was found slightly higher than tha t of CB (200.0 mg g(-1)). Membrane materials of CSB obtained after sque ezing core water from the beads showed approximately 25 times higher volumetric adsorption capacity than CB. (C) 2009 Elsevier Ltd. All rights reserved.
