| Abstract | Starch and sodium humate were utilized as raw material for synthesizing starch-g-poly(acrylic acid)/sodium humate (St-g-PAA/SH) superabsorbent by graft copolymerization reaction of starch (St) and acrylic acid (AA) in the presence of sodium humate (SH) in aqueous solution. The effect of weight ratio of AA to St, initial monomer concentration, neutralization degree of AA, amount of crosslinker, initiator and SH on water absorbency of the superabsorbent were studied. The swelling rate and swelling behavior in NaCl solution as well as reswelling ability of the superabsorbent were systematically investigated. The results showed that the superabsorbent synthesized under optimal conditions with SH content of 7.7?wt% and St content of 11.5?wt% exhibits water absorbency of 1100?g/g in distilled water and 86?g/g in 0.9?wt% NaCl solution, respectively. Introducing SH into the St-g-PAA polymeric network can improved the swelling rate and reswelling capability of the superabsorbent. |
