“…Its performances, especially for large-scale extraction, still need further R&D and optimization; 2) Magnetic separations using magnetic particles grafted with calixarene or AO ligands: this method could have the advantages of high selectivity, easy separation and high degree of material recovery. However, it is still in an early developmental stage; 3) Canal system with braid AO adsorbents: this method, similar to that developed in Japan, appears to be selective and feasible in conjunction with existing technology (25). -calixarene complex (25).…”

“…The studies are focused on the amidoxime based absorbent systems, in the forms of membranes (23) or hydrogels (24). Other systems with resin or magnetic particles grafted with ligands (such as amidoxime or calixarene) are also proposed (25). The work reported by the group in the Desalination Division was carried out under the specific collaboration agreement between the BARC and the CEA (Commissariat à l'Energie Atomique of France).…”

“…Nitrogen and oxygen containing donor functional groups based cross-linked polymers are identified as the most promising candidate among sorbents. Few sorbents such as calixarenes, crown ethers, amidoximebased resins and sorbents (Kawai et al 2000;Choi and Nho 2000;Zhang et al 2003;Sodaye et al 2008) were found to be highly selective towards uranium separation, but they are quite expensive, having low sorption kinetics, and preparation of the sorbents requires instruments such as electron beam radiation grafting, as well as base monomer, i.e. acrylonitrile which is toxic in nature.…”

Solid-phase extraction process using chelating sorbent is a novel technique due to its high separation efficiency and simplicity. A designed three-dimensional crosslinked hydrophilic chelating polymeric sorbent, polyacrylhydroxamic acid, was developed for enhanced uptake of uranium from waste solution (pH 6-9) by complexation between the sorbent's active functional group and uranium. The sorbent was synthesized by polymerization of acrylamide with cross-linking agent, followed by conversion and functionalization with hydroxylamine hydrochloride. In this paper, removal and recovery of uranium from effluent of uranium material processing plant in the presence of competitive ions such as sodium, calcium and magnesium were studied using the sorbent. Uranium uptake property of the developed sorbent was also investigated with respect to sorbent's physical characteristics such as bead size distribution and bead swelling, in batch experiments. Distribution coefficient of uranium in the sorbent was substantially high (1,250 mL of effluent/g of sorbent), and immobilization factor was 0.028. The results showed that more than 90 % recovery of uranium is viable from nuclear effluent without preconditioning. Breakthrough profiles of column operation were successfully described for effective removal of uranium in continuous mode. The novel sorbent has been used for polishing the nuclear wastewater and hence to mitigate the environmental issues.

Desalination brine is a concentrated stream that is generated during the desalination process. Brine commonly has high salinity and TDS (total dissolved ions), which contains ions such as Na+, K+, Ca2+, Mg2+, Cl−, SO42−, HCO3−, PO43−, and some critical elements. Currently, the brine treatment mainly applies direct disposal, like surface water discharge, sewer discharge, deep‐well injection, and evaporation ponds. However, these methods can cause harm to marine ecosystems, soil, and groundwater. Therefore, brine can be regarded as a resource to be reutilized. This work then aims to highlight the novel developments of brine application. For example, Na, Ca, and Mg in brine can be employed for carbon capture and utilization with ammonia, amines, and alkaline substances. With slight adjustment, brine can also be directly used as irrigation water, aquaculture water, and the activation of biochar. Furthermore, brine holds a higher concentration of critical elements, which makes many countries and scholars start to conduct element extraction, reducing the amount of ore exploitation. At last, the major obstacles related to these advancements in sustainability, expenses, and technological aspects are outlined, and promising research trends of brine reutilization are also suggested.
