“…In the RDP study, a total of 0.6 USD was required to prepare 1 g of each of RDP, RDP-FC-Cu, and RDP-FC-Ni. [155][156] However, the selectivity of ion exchange/adsorption was not high because other ions would interrupt the adsorption and desorption processes. Solvent extraction can be used to efficiently separate Li from brine without other impurities, but it is expensive because of the required apparatus and chemicals.…”

“…provided three adsorbents called roasted date pits (RDP), potassium copper, and nickel hexacyanoferrate‐date pits (RDP‐FC‐Cu and RDP‐FC‐Ni) for Li recovery from desalination brine. [ 156 ] Enhanced adsorption of Li onto the three adsorbents was observed as the solution temperature and initial Li concentration increased. The optimal temperature for the highest Li adsorption onto the three adsorbents was found to be 45 °C, and the greatest adsorption of Li ions onto these adsorbents occurred at an initial Li concentration of 100 mg L −1 .…”

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.
