Abstract
Discusses the permeability modulation of Supported Magnetic Ionic Liquid Membranes (SMILMs) for CO₂ separation, when applying an external magnetic field. Researchers examined four magnetic ionic liquids (MILs), ([P₆₆₆₁₄][CoCl₄], [P₆₆₆₁₄][FeCl₄], [P₆₆₆₁₄][MnCl₄] and [P₆₆₆₁₄][GdCl₆]), in combination with a commercial hydrophobic PVDF porous support.
They conducted an experimental evaluation of membrane permeability for CO₂, N₂ and air. They also investigated the influence of the magnetic field on MILs viscosity, in order to establish the relationship between permeability and viscosity depending on the external magnetic field.
