Cellulosic superabsorbents (SAP) are produced by using
cellulose and cellulose derivative blends with different binding methods,
generally. But cellulose in SAP leads
decrease in water absorption and water bonding ability because of nonreactive
character of cellulose based on its chemical structure. The oxidative
pretreatments of cellulose were attempted for the resolve of disadvantage of
cellulose in SAP, in this study. Hydrogen peroxide and TEMPO (2,2,6,6-
tetramethylpiperidine-1-oxyl) were used for oxidative pretreatments of cellulose.
Oxidized cellulose and carboxymethylcellulose (CMC) blended and cross-linked by
epicholohydrin for cellulosic SAP production. Water absorption capacity of
cellulosic SAP were determined in pH:2, 7 and 10. The results show that the
oxidative pretreatments of cellulose had affirmative effect of water absorption
capacity of cellulosic SAP according to control samples.
