| Abstract Scope |
The increase in demand for critical raw materials to attend the green energy sector has highlighted the challenges for the supply chain. Primary and secondary sources have been identified, and processes are being developed. However, novel techniques are necessary for the extraction of critical metals. Supported liquid membranes bring advances from membrane and solvent extraction separation. The present study aims to evaluate supported liquid membranes on separating Ni-Co and La extraction. Experiments were carried out in batch and the effect of pH and time were evaluated. The effect of gradient- and electric-driven forces were compared. The effect of pH was on the solvent extraction process, and the electric-driven force increased the ions fluxes but decreased selectivity. A flowchart is proposed for future studies and upscaling of the supported liquid membrane separation technique. |
