Abstract

The present work evaluates the influence of magnetic field on the transport of two model organic compounds, ibuprofen and α - pinene, through supported magnetic ionic liquids membranes (SMILMs). The membranes studied were prepared by incorporation of magnetic ionic liquids (MILs), [C₁₁H₂₁N₂O]₃ [GdCl₃Br₃], [C₄mim] [FeCl₄] and [C₈mim] [FeCl₄]. Transport studies were conducted in the absence and presence of a magnetic field with an intensity of 1.2T. The results obtained show that the magnetic field increases the diffusion coefficient of ibuprofen and α - pinene, improving their transport through the SMILM. The two transport studies performed, α - pinene in dodecane through a SMILM with [C₄mim] [FeCl₄], and α - pinene in hexane through a SMILM with [C₈mim] [FeCl₄], revealed a permeability increase of 51% and 29% respectively when exposed to the magnetic field, whereas transport studies of ibuprofen in dodecane through [C₁₁H₂₁N₂O]₃[GdCl₃Br₃] MIL showed a permeability increase of 59% under the same magnetic field conditions. The analysis of the magnetic field influence on solute permeation revealed that the permeability increase observed cannot be solely interpreted due to a decrease of MILs viscosity induced by the magnetic field. The magnetic dependence of solutes solubility in the MILs should also be considered.
