Cover Story: Hydrogels are water-swollen polymer networks widely applied in wastewater treatment. Carrageenan, a sulfated polysaccharide, provides abundant anionic groups for cationic dye adsorption, but conventional metal-ion cross-linking reduces their availability. Cellulose offers mechanical strength, yet lacks ionic functionality. To overcome these limitations, κ-carrageenan/cellulose hydrogel beads were prepared using an ionic liquid mixture without metal-ion cross-linkers. This strategy preserved sulfate groups, enhanced adsorption sites, and yielded stable interpenetrating networks. The beads were systematically evaluated for swelling, pH tolerance, reusability, and adsorption of crystal violet as a model cationic dye, including kinetic, isotherm, and thermodynamic studies. The results show their potential as sustainable and efficient adsorbents for cationic dye. View this paper
