چکیده

This study presents the development of a novel biocompatible polymer-based iron nanocomposite hydrogel. The synthesis involved grafting acrylic acid onto a cellulose backbone with simultaneous cross-linking. Methylenebisacrylamide was employed as a cross-linking agent, potassium persulfate was employed as a thermal initiator, and iron nanoparticles were incorporated as filling and reinforcing agents. A systematic optimization of factors affecting water absorption was conducted to achieve a superabsorbent with maximum swelling capacity. The efficacy of the synthesized iron hydrogel nanocomposite in the adsorption of crystal violet dye as a model cationic dye was investigated. The study examined the influence of various parameters on removal efficiency, including initial dye concentration, adsorbent dosage, contact time, and temperature. Additionally, thermodynamics, kinetics, and adsorption isotherms were analyzed. Results indicated that the adsorption method adheres to second model kinetics and the Langmuir adsorption isotherm. Based on experimental findings, the iron nanocomposite hydrogel demonstrates promising potential for environmental pollutant removal, particularly in eliminating toxic compounds from aqueous solutions.
