Title:
マイクロ波による膜透過制御方法
Document Type and Number:
Japanese Patent JP5025844
Kind Code:
B2
Abstract:
The present invention relates to a method for controlling a permeability of a substance to be separated through an organic separation membrane in a separation process of substances by an organic separation membrane, characterized in that the method comprises irradiating the organic separation membrane with a high frequency wave to cause vibration/rotation of a molecule or a domain thereof constituting the organic separation membrane and alter the molecular structure and/or polarity of the organic separation membrane, and thus altering a permeability of the substance to be separated; and also a method for producing an organic separation membrane, characterized by irradiating with a high frequency wave in a process of producing the organic separation membrane to alter the permeability thereof.
