Efficient precipitation of dyes from dilute aqueous solutions of ionic liquids.
The addition of only approximately 1.7 wt% (approximately 0.06 M) ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate to aqueous solutions of six popular cationic dyes resulted in the precipitation of almost all of the dye from the solution.
