Rare earth metal separation with new amide functionalised ionic liquids: understanding species and selectivity Ciaran Carroll (24165066) PUREID: 304708419 Ionic liquids rare-earth metals lanthanides Recycling rare-earth metals from end-of-life products such as hard-drive magnets is of critical importance particularly in the face of growing demand for consumer goods and other applications. Liquid-liquid extraction is the preferred method of separation utilising organic extractants owing to their scalability and commercial potential. The use of volatile diluents is a major safety concern in these large separation processes. Task-specific ionic liquids have been developed in response, benefiting from their negligible vapour pressure offering an alternative for liquid-liquid rare-earth metal separation.<br><br>The work presented in this thesis aimed to develop the multifunctional amide ionic liquid, [MAIL][NTf2], for extraction of rare-earth metals from waste magnet feeds, specifically separation of dysprosium(III) and neodymium(III). In addition to designing and synthesising new generations of extractants with the hope of developing superior extractants.<br> 2026-10-01T17:10:32Z Text Thesis 10.17034/32632554.v1 https://figshare.com/articles/thesis/Rare_earth_metal_separation_with_new_amide_functionalised_ionic_liquids_understanding_species_and_selectivity/32632554 All Rights Reserved
