چکیده SBA-15 mesoporous materials modified by sulfonic acid and sulfamic acid functionalities, abbreviated as SBA-15/SO3H and SBA-15/NHSO3H, were synthesized and applied for the removal– separation of Eu(III), Th(IV), and U(VI). SBA-15/NHSO3H showed an excellent selectivity toward U(VI), while SBA-15/SO3H was more efficient adsorbent for Eu(III) and Th(IV). It was found that in the presence of KNO3(1 mol L −1 ), the separation of Eu(III)/Th(IV) from their mixtures is possible. The results of the sorption behavior indicated a high adsorption capacity toward U(VI) and Th(IV) ions (140.5 and 106.7 mg g −1 , respectively) and ultrafast kinetics (15 min) in Eu(III) adsorption.
