<p>A method for controlling the permeability of a substance to be separated through an organic membrane for separation, in a process of separating substances by the organic membrane, characterized in that it comprises irradiating the organic membrane with a high frequency wave, thereby causing vibration/rotation of a molecule or a domain of molecules constituting the membrane and thus changing the molecular structure and/or polarity of the membrane, to change the permeability of the substance to be separated through the membrane; and a method for producing an organic membrane for separation, characterized in that the permeability of the organic membrane is controlled through irradiating the membrane with a high frequency wave in a process of forming the membrane.</p> |
