Summary: We developed an adsorption column using a functional ligand grafted onto amino silica gel for rare earth recovery from acid mine drainage. The optimized operating conditions were determined to be a flow rate of 500 μL min-1 and an eluent of pH=2 with 0.013 mol L-1 DTPA. The recovery of rare earth metals from actual AMD achieved high percentages and the purity of rare earth in AMD increased significantly after recovery. Furthermore, detailed investigations were conducted on the thermodynamics, kinetics, adsorption mechanism, and theoretical calculations of the adsorption process.

Summary: The aim of this work is to investigate the efficacy of using molecular imprinting technique to create selective macromolecular sorbents for the sorption and separation of light and heavy rare-earth metals such as samarium and gadolinium. The advantage of these sorbents lies in their ability to selectively sorb only the target metal due to the formation of complementary cavities during the synthesis of molecularly imprinted polymers, thereby avoiding the concomitant sorption of metals with similar properties. Two types of molecularly imprinted polymers were synthesized using methacrylic acid (MAA) and 4-vinylpyridine (4VP) functional molecules. The sorption properties and the effect of template removal cycle count on sorption effectiveness were studied, and laboratory experiments on selective sorption and separation of samarium and gadolinium from a model solution were conducted.

Summary: This study analyzed the structure, lithium capturing efficiency, and energy consumption of Li, Mn, and Ti spinel-type materials in the HCDI system, identifying the spinel with a Li:Mn:Ti ratio of 1:3:0.15 as the best material for lithium recovery. Testing with natural geothermal water showed a lithium capturing efficiency near 80% in 8 minutes, with separation factors for other cations over three times smaller.

Summary: Heavy metals and rare earth elements are widely used in various industrial and technological applications, but their release into the environment can have harmful effects. There is increasing interest in detecting and recovering these elements due to their environmental impact and economic importance. Various methods, including sensors and sorbents, are being developed, but they have limitations such as complex sample pretreatment and potential environmental pollution. Recently, eco-friendly biomolecules, especially aptamer-based materials, have been developed as promising alternatives for detecting and recovering these elements in water.

Summary: The properties of rare-earth-metal ions in aqueous media depend on their hydration modes, which can be fixed by encapsulating them in a hydrophobic cavity. Counter anions play a crucial role in capturing the ions at a fixed position. Early lanthanoid ions were preferentially encapsulated even with the same hydration number and geometry.

Summary: In this study, a new biosorbent (MNPLanM) was developed by immobilizing Lanmodulin-SpyCatcher on the surface of SpyTag-functionalized magnetic nanoparticles (MNPs) for selective separation and recovery of rare earth elements (REEs) from waste streams. The biosorbent exhibited high adsorption activity and fast kinetics, and the adsorbed REEs could be efficiently desorbed. MNPLanM selectively adsorbed REEs in the presence of non-REEs and showed high stability after multiple adsorption-desorption cycles. Furthermore, MNPLanM effectively concentrated REEs from low-grade feedstocks, achieving a significant increase in REE purity.

Summary: Efficient and sustainable secondary sourcing of Rare-Earth Elements (REE) is important to address supply bottlenecks and the negative impacts of primary mining. Recycling electronic waste (E-waste) is a promising source of REE, and hydrometallurgical methods followed by chemical separation techniques have successfully been used to recover REE from these wastes. However, the generation of unsustainable acidic and organic waste streams has led to the exploration of greener approaches, such as sorption-based technologies using biomass. Algae sorbents have gained attention, but the efficiency of sorption is influenced by various factors, including biomass type, solution parameters, and matrix complexity.

Summary: Rare earth elements (REE) are critical metals with high supply risk and growing demand. Waste electrical and electronic equipment (WEEE) is a potential secondary source for recovering REE, but there are challenges and gaps in the recovery process. Hydrometallurgical processes using sulfuric acid have been mainly studied, and sequential processes and recovery from different residues are lacking.
