英文摘要	Vinyl-functionalized sodium alginate (VSA) was used as matrix and crosslinker to fabricate VSA-co-methylacrylic acid-co-italic acid (VSA-co-MAA-co-IA) nano-porous hydrogels using micelle/emulsion asthe pore-forming template.¹H NMR,¹³C NMR, FTIR and UV–vis analyses proved that vinyl groups wereintroduced to SA backbone, and the VSA was reacted with the vinyl monomers by a free-radical poly-merization to form a hydrogel network. The nano-pores can be uniformly formed in the hydrogels byintroducing micelle template as shown by FESEM observations. The absorption properties of the hydro-gels for Pb²⁺ions were investigated by evaluating the absorption isotherm and absorption kinetics. Resultsshowed that the hydrogel has higher absorption capacities for Pb²⁺ion (432.28 mg/g for 880 mg/L Pb²⁺solution and 765.75 mg/g for 2800 mg/L Pb²⁺solution), and the formation of nanoporous structure clearlyenhanced the absorption rate by 32.56% (for 880 mg/L Pb²⁺solution) and 36.79% (for 2800 mg/L Pb²⁺solution).
