Abstract

To separate Mo(VI) from high-level liquid waste, a silica-based (anti-DEHDO + Dodec)/SiO₂-P adsorbent was synthesized by impregnating an anti-isomer of 5,8-dietyl-7-hydroxy-6-dodecanonoxime (DEHDO) as a hydroxyoxime-type extractant and a molecule modifier of 1-dodecanol into a SiO₂-P support, where “P” indicates the polymerized styrene–divinylbenzene inside macroporous SiO₂ particles. Adsorption and separation behaviors of Mo(VI) in HNO₃ solutions onto the adsorbent were investigated by batch and column methods, respectively. The adsorbent can effectively adsorb Mo(VI) in both methods. In addition, Pd(II) and Zr(IV) contained in the simulated high-level liquid waste were successfully isolated by the adsorbent packed column, respectively.
