摘要： The installation for separating a multivalent cationic species from a solution comprising this multivalent cationic species and lithium comprises a capture device (3) having an entry (2) and an exit (4). The capture device (3) comprises, between the entry (2) and the exit (4), a microfibre product (12) with a higher affinity for multivalent cations than for monovalent cations. The installation comprises a circulation system (5) adapted to circulate the solution from the entry (2) to the exit (4) in contact with the microfiber product (21), the microfibre product (21) capturing said multivalent cationic species.

摘要： Silver is recovered as Ag0 nanoparticles from the spent solution obtained from the regeneration of an Ag-loaded ion exchange resin using electrolysis. The reclaimed regenerant solution is recycled and reused in a closed-loop scheme over multiple cycles. The recovered Ag0 nanoparticles are monodisperse, spherical in shape, and have a mean diameter of about 6 nm.

摘要： Methods, sorbent cartridges and cleaning devices are disclosed for refurbishing sorbent materials. In one implementation among multiple implementations, a medical fluid delivery method includes: providing a sorbent cartridge including H+ZP within a casing for a treatment; and after the treatment, refurbishing the H+ZP while maintained within the casing via (i) regenerating the non-disinfected H+ZP by flowing an acid solution through the casing, (ii) rinsing the regenerated H+ZP while maintained within the casing, (iii) disinfecting the regenerated and rinsed H+ZP by flowing a disinfecting agent through the casing, and (iv) rinsing the regenerated and disinfected H+ZP while maintained within the casing. Multiple batch sorbent refurbishing implementations are also disclosed.

摘要： 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.

摘要： A composite extractant-enhanced polymer resist comprising an extractant and a polymer resin for direct extraction of valuable metals such as rare earth metals, and more specifically, scandium, Born an acid-leaching slurry and/or acid-leaching solution in which ferric ions are not required to be reduced into ferrous ions. The extractant may be cationic, non-ionic, or anionic. More specifically, the extractant di(2-ethylhexyl)phosphoric acid may be used. The polymer resin may be non-functional or have functional groups of sulfonic acid, carboxylic acid, iminodiacetic acid, phosphoric acid, or amines. The composite extractant-enhanced polymer resin may be used for extraction of rare earth metals from acid-leaching slurries or solutions.
