Abstract:

Ionic liquids (ILs) and deep eutectic solvents (DESs) are gaining prominence as next-generation solvents in solution chemistry, offering a unique combination of tunable structures, negligible vapor pressure, and exceptional thermal and chemical stability. These properties, along with their superior solvating power and ionic conductivity, position them as ideal candidates for advancing sustainable separation and extraction technologies.

This talk will explore how the molecular-level tailoring of ILs and DESs can be leveraged to optimize their physico-chemical properties for enhanced performance in sorption and extraction processes. Case studies will highlight their effectiveness in critical applications such as wastewater treatment, selective metal recovery from electronic waste and spent lithium-ion batteries, and biomass valorization.

Particular attention will be given to their environmental advantages over conventional solvents, including reduced toxicity, reusability, and compliance with green chemistry and circular economy principles. By examining recent advances and emerging trends, this presentation aims to illuminate the transformative potential of ILs and DESs in driving sustainable innovation across chemical industries.
