The nanocomposite hydrogels based on kappa–carrageenan (Carra) and sodium alginate (Na–Alg) biopolymers were synthesized from solution polymerization of acrylamide (AAm) monomer and methylenebisacrylamide (MBA) crosslinker using sodium montmorillonite (Na–MMt) nanoclay. The obtained nanocomposites were used to remove the cationic crystal violet dye from water. The effects of Carra and Na–Alg weight ration as well as the Na–MMt content on the dye adsorption capacity of nanocomposites were evaluated. In compared to hydrogel with no–clay, the results showed that the inclusion of Na–MMt nano–clay into hydrogels caused an increase in dye adsorption of hydrogels. Also, the increase in Carra to Na–Alg ration caused an increase in dye adsorption capacity.<\div>
