Method for removing or detoxifying gas

Abstract

A method for removing negatively-charged gas molecules includes the steps of: adsorbing negatively-charged gas molecules by a substrate carrying a positively-charged substance or a positively-charged substance and a negatively-charged substance on the surface of the substrate or in a surface layer of the substrate; and desorbing the aforementioned negatively-charged gas molecules adsorbed on the aforementioned substrate, from the substrate using a fluid. According to the present invention, negatively-charged gas molecules are removed or detoxified by adsorbing the same by a substrate carrying a positively-charged substance, or a positively-charged substance and a negatively-charged substance, on the surface of the substrate. Thereby, it is possible to provide a simple process by which negatively-charged gas molecules are able to be effectively and economically removed or detoxified.
