Adsorption and separation of RNA and protein on imidazolium-type ionic liquids-based chromatographic media: influence of counterions.

Imidazolium-based ionic liquids (ILs) as ligand have shown great potentials in biomacromolecule separation by chemically coupling the cationic functional group of the ILs to solid supports. Whether and how the counterions affect the adsorption of bio…
