Abstract

Water pollution is one of the serious global issues caused by expanding urbanization and industrialization. Over the last few decades, various adsorbents have been developed to improve water quality and address future challenges of water pollution. Among them, the development of hydrogel-based adsorbents has received significant attention due to their hydrophilic nature, 3D formation, high porosity, non-toxic properties, reusability, and multifunctionality. Therefore, this review provides various types and characterizations of hydrogel and summarizes recent progress in the use of hydrogel adsorbents for the removal of water contaminants. Further, we introduced the preparation of hydrogel-based adsorbents, their adsorption capacity, and the development of multifunctional adsorbents for discussing the future direction of advanced adsorbents.

무분별한 도시화와 산업화로 인해 발생된 수질오염은 국제적으로 심각한 문제 중 하나이다. 지난 몇십 년 동안, 수질 환경 개선과 앞으로의 수질오염으로부터 대처를 위해 다양한 흡착제가 개발되어 왔다. 이 중에서, 하이드로겔 기반 흡착제 개발은 친수성 성질을 바탕으로 3차원 구조를 형성하며 높은 다공성, 무독성, 재사용성, 그리고 다기능성 때문에 많은 관심이 집중되고 있다. 본 총설에서는 흡착제 개발을 수행함에 있어 하이드로겔의 종류 및 특성을 알아보고, 최신연구들을 소개하고자 한다. 추가적으로 하이드로겔 흡착제의 제조, 다양한 오염물질 제거능력, 그리고 다기능성 흡착제에 대해 소개함으로써 앞으로의 첨단 흡착제 개발방향에 대해 논의하고자 한다.
