Used as an effective extractant in hydrometallurgy for the separation and recovery of valuable metals such as cobalt, nickel, and rare earth elements from aqueous solutions. It shows high selectivity and efficiency in solvent extraction processes, particularly in acidic environments. Its ability to form stable complexes with metal ions makes it suitable for purifying and concentrating metals from leach solutions in recycling and mining operations. Also investigated for use in membrane-based separation techniques and sensor development due to its ion-binding properties.
