Abstract:
In recent years, the importance of rare earth elements (REEs) has become increasingly important due to their unique properties, limited availability, and numerous applications, especially in modern technologies. Therefore, alternative sources of these elements are sought, especially among industrial wastes, such as coal fly ash, which can become their excellent secondary source [1, 2]. In this work, the use of modern hybrid adsorption membranes for rare earth metal ion recovery was proposed [3]. The adsorption membranes were produced by the method of magnetic casting from a 2-component solution of polymers imprinted with the appropriate REE ion with the appropriate addition of functionalized MWCNT-ILs (0.5 - 5% wt.). The formed membranes were tested for their application in the recovery of selected REE ions from synthetic solutions corresponding to the composition of real extracts obtained during the leaching of REE ions from coal fly ash. Characteristic separation parameters were determined, such as selectivity, REE recovery, and adsorption capacity.
