The membranes studied were prepared by incorporation of magnetic ionic liquids (MILs), [C11H21N2O] [GdCl3Br3], with [C4mim] [FeCl4] and with [C8mim] [FeCl4]. Transport studies were conducted in the absence and presence of a magnetic field with an intensity of 1.2 T. 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 C11H21BrCl3GdN2O 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.Pracoviště Ústav chemických procesů Kontakt Eva Jirsová, jirsova@icpf.cas.cz, Tel.: 220 390 227 Rok sběru 2016
