Highly efficient extraction of methyl red by a novel Kappa carrageenan hydrogel

A novel kappa carrageenan hydrogel was synthesized and evaluated as an adsorbent for its swelling behavior towards the azo dye (methyl red) which was selected as test dye species. The kappa carrageenan hydrogel was employed as a novel adsorbent that offers high swelling behavior, magnetic separate ability and good stability. Adsorption experiments were carried out as batch studies at different conditions. The dye adsorption equilibrium was rapidly attained. Removal of dye in acidic solutions was better than in basic solutions
