Supramolecular Ionic Liquid Gels as Sorbents for Bisphenol-A Removal

The removal of emergent pollutants like endocrine disrupting compounds (EDC) from wastewaters is a pressing issue of contemporary times.1 An efficient and low-cost strategy involves the adsorption of pollutant onto suitable nanostructured materials. In this context, supramolecular gels, originated by the self-assembly of small molecules in solution, are receiving increasing interest, due to their high adsorption ability, selectivity and often high recyclability.2 In the light of this, in the framework of our interest in supramolecular gels in nonconventional solvents,3 we obtained and characterized supramolecular gels of 1,3:2,4- dibenzylidene-D-sorbitol (DBS) in aromatic and aliphatic ionic liquids, reported in Figure 1.
