ABSTRACT:
An element for adsorbing one or more active gases in an inert gas to obtain an inert gas such as air containing an inert gas such as air containing an ultra-low concentration active gas such as water vapor. The element is produced by laminating low density papers composed of inorganic fiber to form a matrix in the form of a gas adsorbing element having numerous small channels penetrating through opposite surfaces, impregnating the matrix with water glass in which synthesized zeolite powder is dispersed, and soaking the matrix in aqueous solution of aluminum salts, magnesium salts or calcium salts, and so on, to form metal silicate hydrogel on the paper and in the apertures between fibers of papers, and washing and drying the matrix and the metal silicate hydrogel to obtain the element. The main constituent of the element being synthesized zeolite and metal silicate aerogel deposited on the inorganic fiber matrix.
