Description
Summary:The magnetite embedded mesoporous silica was prepared and functionalized with succinic acid, (abbreviated as Fe-MCM-SUC) for targeted adsorption of uranium from aqueous solution. The adsorbent Fe-MCM-SUC was characterized with various advanced spectroscopic and analytical techniques and its adsorption performance towards uranium was evaluated under different conditions of aqueous medium. An apparent uranium adsorption capacity of 430 mg·g −1 was observed from pH ≥ 6 solution. The adsorbed uranium was recovered easily using dilute Na 2 CO 3 solution and the recovered adsorbent was tested for uranium adsorption in multiple cycles for checking the feasibility of regeneration . The results showed that the adsorbent, Fe-MCM-SUC, is a potential candidate for the recovery of uranium from aqueous solution.
