Abstract: In alternative embodiments, the invention provides processes and methods for the recovery, removal or extracting of, and subsequent purification of uranium from a wet-process phosphoric acid using a continuous ion exchange processing approach, where the uranium is recovered from a phosphoric acid, or a phos-acid feedstock using either a dual or a single stage extraction methodology. In both cases an intermediate ammonium uranyl-tricarbonate solution is formed. In alternative embodiments, in the dual cycle approach, this solution is contacted in a second continuous ion exchange system with a strong anion exchange resin then subsequently recovered as an acidic uranyl solution that is further treated to produce an intermediate uranyl peroxide compound which is ultimately calcined to produce the final uranium oxide product. In alternative embodiments, in the single cycle case, the intermediate ammonium uranyl-tricarbonate solution is evaporated to decompose the ammonium carbonate and produce an intermediate uranium carbonate/oxide solid material. These solids are digested in an acid medium, and then processed in the same manner as the secondary regeneration solution from the dual cycle process to produce an intermediate uranyl peroxide that is calcined to produce a final uranium oxide product.

Abstract: A functionalized polymeric separator membrane, including a polymer backbone chosen from an aramid-based polymer, a polyamide-based polymer, or a polyimide-based polymer, or combinations thereof; and further comprising one or more functional side groups (-FSG) capable of trapping transition metal ions and acidic species. The functionalized polymeric separator membrane may be a sulfonated polyaramid separator membrane. Sulfonation of polyaramid separators add functional groups that trap both acidic species and TM ions, thereby suppressing anode damage caused by TM deposition onto the anode by a two-step process. The functionalized polymer separator membranes may be used with Li-ion, Li-metal, or Sodium-ion batteries.

Abstract: The present invention discloses two component cross-linked copolymers in bead form wherein the cross-linked copolymer of the first component formed in the first step has lower cross-linker content than the cross-linker content in the cross-linked copolymer of the second component formed in the second step. These beads are further functionalized to yield strong acid cation exchange resins, strong base anion exchange resins and weak acid cation exchange resins. Ion exchange resins so synthesized exhibit operating exchange capacity (OEC) to total exchange capacity (TEC) ratio in the range of 49 to 61% and also retain more than 85% of whole bead count when subject to osmotic shock resistance test to simulate performance in usage. These ion exchange resins offer advantages in applications such as water treatment, condensate polishing, and unit operations in non-water application like drug purification, sugar processing, catalysis etc.
