Polysulfone (PSF) microcapsules containing ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) as extractant have been successfully prepared using solvent evaporation method and used in removing caprolactam from water. The results showed that ionic liquid [Bmim][PF6] was successfully encapsulated by PSF and the encapsulation capacity of 32.44% was achieved. Systematic studies...
In this paper, investigations have been carried out to determine the suitability of imidazolium-based ionic liquids (ILs), 1-alky-3-methylimidazolium hexafluorophosphate [C n mim][PF 6 ] (n=4, 6, 8), 1-hexyl-3-methylimidazolium tetrafluoroborate [C 6 mim][BF 4 ] and 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [C 4 mim][NTf 2 ], in replacing...
