In this study, a new cationic P(AAm-AETAC) hydrogels were prepared by a radical addition reaction in aqueous solution with acrylamide and [2-(acryloyloxy)ethyl] trimethylammonium chloride) comonomers in the presence of ethylene glycolmethacrylate. Hydrogels were characterized by spectroscopic, surface, and thermal analysis. The hydrogel does not undergo any structural degradation with the effect of heat up to 250 oC.
The adsorption of titan yellow from aqueous solution to the newly prepared cationic hydrogels was evaluated by Freundlich, Langmuir, and Temkin isotherms. The dye adsorption to hydrogels prepared from adsorption isotherms was L type according to the Giles adsorption isotherms. It was determined that the adsorption of titan yellow to the hydrogels prepared from the RL values calculated for a concentration of 500 mg L-1 titan yellow was favorable. The dye removal efficiency of the hydrogel from the aqueous solution was found to be about 98%. As a result, it can be said that the cationic P(AAm-AETAC) hydrogel, which is prepared at a low cost, can provide a high amount of removal in the adsorption of anionic dyes from aqueous solutions.
