A new stripping and recovery process was developed to harvest the uranium recovered from seawater with amidoxime-functionalized polyethylene fiber sorbents and allow reuse of the sorbent without loss of capacity and without the need to recondition the sorbent before reuse. Hydroxylammonium acetate ([NH3OH][OAc])/aqueous acetic acid (AcOH) solutions were used as weakly acidic stripping agents and the stripped uranium as a soluble acetate was further immobilized on shrimp shells. These solutions also stripped the vanadium and other metal ions coadsorbed, which reduce capacity through competition with uranium for sorbent binding and can resist stripping even by strong acids. [NH3OH] [OAc]/AcOH was found to allow recovery of more than 85% of the uranium although at a substantially longer time than the current 0.5 M HCl-stripping solutions, (less than 12 h vs 48-72 h, respectively); however, the use of HCl severely compromises the capacity of the sorbent in subsequent reuse (a 50% lost was observed on the third reuse of the fiber). Both [NH3OH] [OAc] and the acetic acid were necessary to achieve high uranium recovery without sacrificing the sorbent's capacity on reuse. The ability to reuse the sorbent without pretreatment and with minimal capacity loss could be an important step toward making the extraction of uranium from seawater energy-efficient and economically viable.
