摘　　要：综述了多系列水凝胶功能化方法 (包括化学改性法、接枝共聚法、纳米复合法和构建多重网络法)及其对水中典型重金属的吸附特性,重点总结了纳米复合法和构建多重网络法对水凝胶吸附特性、稳定性等强化规律和原理,进一步展望了功能化水凝胶的发展方向以及高效、稳定、廉价、高选择性等特征需求,为水凝胶的创新研发及其实际应用提供了参考和指导。Various functionalized hydrogels prepared by chemical modification, graft copolymerization, nanocomposite and multiple-network construction and the corresponding adsorption characteristics of heavy metal ions were reviewed. The enhanced laws and principles of adsorption, stability and other characteristics of nanocomposite and multiple-network construction were highlighted. The design and synthesis of hydrogels with high efficiency, good stability, low cost and outstanding selectivity were the development direction of functionalized hydrogels for heavy-metal removal. This review provides reference and guidance for the innovation and practical application of hydrogels.
