Over the last few decades, various adsorption functions of polymer hydrogels for the removal of hazardous pollutants have been developed. The performance of hydrogel adsorbents depends on the constituents of the gels and the functions produced by the polymer networks of the gels. Research on hydrogels utilizing the characteristic functions of polymer networks has increased over the last decade. The functions of polymer networks are key to the development of advanced adsorbents for the removal of various pollutants. No review has discussed hydrogel adsorbents from the perspective of the roles and functions of polymer networks in hydrogels. This paper briefly reviews the basic requirements of adsorbents and the general characteristics of hydrogels as adsorbents. Thereafter, hydrogels are reviewed on the basis of the roles and functions of the polymer networks in them for the removal of hazardous pollutants by introducing studies published over the last decade. The application of hydrogels as adsorbents for the removal of hazardous pollutants is discussed as well.
在过去几十年中，已经开发出了聚合物水凝胶用于去除有害污染物的各种吸附功能。水凝胶吸附剂的性能取决于凝胶的成分以及凝胶聚合物网络产生的功能。在过去十年中，利用聚合物网络特征功能的水凝胶研究有所增加。聚合物网络的功能是开发用于去除各种污染物的先进吸附剂的关键。目前尚无综述从聚合物网络在水凝胶中的作用和功能角度讨论水凝胶吸附剂。本文简要回顾了吸附剂的基本要求以及水凝胶作为吸附剂的一般特性。此后，通过介绍过去十年发表的研究，根据聚合物网络在其中的作用和功能对水凝胶进行综述，以去除有害污染物。还讨论了水凝胶作为吸附剂去除有害污染物的应用。
