Jiangsu University · Chinese Academy of Sciences · +1 more institution
Abstract
The rapid pace of global industrialization and population growth has intensified freshwater scarcity and water pollution, necessitating urgent solutions. Adsorption technology, favored for its cost-effectiveness, simplicity, and scalability, has emerged as a promising approach. Hydrogels, particularly cellulose-based hydrogels (CBHs), have gained significant attention as green adsorbents due to their biodegradability, non-toxicity, low cost, and exceptional adsorption capacity. This paper reviews recent advancements in CBHs for sustainable wastewater treatment, focusing on synthesis techniques, performance, and mechanisms for removing heavy metals, dyes, and micropollutants. Updated applications and their…
