ملخص

Natural biopolymers are better adsorbents due to better functionality, surface area, bio-compatibility and ease of procurement. The gum arabic in natural biopolymer derived from Acacia Arabic species. In the present work a novel nanohydrogel of gum arabic with acrylamide has been fabricated using microwave synthesis for adsorption of noxious crystal violet dye from aqueous medium. The prepared gum arabic-cl-poly(acrylamide) nanohydrogel (GA-cl-poly(AAm)) NHG was characterized by numerous techniques including SEM, XRD, TEM and FTIR. The GA-cl-poly(AAm) NHG showed promising adsorption ability for crystal violet dye. The effect of various adsorption factors such as concentration of GA-cl-poly(AAm) NHG and crystal violet, pH, temperature and time has been studied and reported. For understanding the adsorption mechanism three models Langmuir, Freundlich and Temkin were applied to adsorption data The kinetics and thermodynamics of adsorption were also investigated The adsorption capacity of crystal violet onto GA-cl-poly(AAm) NHG according to Langmuir model is found to be 90.90 mg/g.
