Özet
The research in biopolymer-based superabsorbents is gaining importance in the green chemistry feld thanks to their environmentally friendly properties. In this study, a biopolymer-based superabsorbent made of calcium ion crosslinked alginate/
carboxymethyl cellulose composite was prepared by a new quasi-cryogelation process, where the complete ionic gelation
takes place before the freezing step, in contrast to the conventional cryogelation technique in which gelation occurs under
semi-frozen conditions. Thanks to the facile quasi-cryogelation method, the morphology of the gels changed and a signifcant increase in water absorption properties has been achieved. The swelling properties of the material were investigated
in distilled water and diferent physiological fuids. Results show that the proposed material shows good water absorption
property where a water absorption of 2343% was reached and even after fve cycles this value was 1200%. As a result, this
study reports a biopolymer-based sustainable superabsorbent which is appropriate for various applications such as the removal
of pollutants from water or diaper production.
