摘要：
A granular hydrogel was prepared under ambient conditions using chitosan as the graft backbone, acrylic acid as the monomer, and ascorbic acid/hydrogen peroxide (Vc/H2O2) as the redox initiator, and then crosslinked with Fe3+ ions. The resulting Fe3+-hydrogel was tested for the catalytic reduction of 4-nitrophenol (4-NP), with the finding that in the presence of NaBH4 and an inert atmosphere, 5 mg/L 4-NP can be completely reduced by Fe3+-hydrogel within 30 min. Also, Fe3+-hydrogel exhibits an excellent reusability for ten successive catalytic cycles.
