A comparative investigation of uranium and thorium adsorption behavior on amidoximated copolymeric hydrogel

Abstract This work focuses on investigating the feasibility of using a crosslinked amidoximated copolymeric hydrogel as potential adsorbent to recover uranium and thorium ions from aqueous media. The was synthesized via gamma-irradiation copolymerization characterized through FTIR, TGA, SEM. medium acidity notably affected adsorption capacity both ions. data in line with pseudo-1st-order equation Freundlich isothermal model. thermodynamics analysis showed that temperature rise promoted capacity. reusability studies highlighted good performance up five regeneration rounds.
