Abstract
Hydrogels possess remarkable physicochemical properties, including high water absorption, retention capacity, and controlled degradation. Simultaneously, their biocompatible, biodegradable, and non-toxic nature makes them highly suitable for diverse water treatment applications, encompassing adsorption, filtration, and membrane separation. In this review, recent advancements in cellulose-based hydrogels, including methods of synthesis, modification, and characterization, are reviewed. Furthermore, the various applications of cellulose-based hydrogels in water treatment and purification are discussed in detail. This includes the adsorption of heavy metals, dyes, and organic pollutants, as well as membrane separation and desalination. The paper also highlights the challenges and opportunities for developing and utilizing sustainable cellulose-based hydrogels in water treatment and purification. Moreover, it offers a detailed and well-organized analysis of sustainable hydrogels made from cellulose by exploring their potential uses in water treatment and purification. It provides valuable insights into the potential use of cellulose-based hydrogels for sustainable and effective water treatment solutions.
