Abstract
PURPOSE: To effect a restriction-free, industrial scale treatment by a method wherein fluorine contained in gas is absorbed in two stages, first using adsorbent added with crystalline aluminum hydroxide, then using adsorbent added with amorphous aluminum hydroxide.
CONSTITUTION: Fluorine ingredient contained in gas is absorbed in prestage absorption process using absorbent at a pH 1 or less and added with commercially available crystalline aluminum hydroxide or alumina which is not resitriced in quantity. The remaining fluorine is then absorbed in poststage absorption process using adsorbent at pH 1W4 added with amorphous aluminum hydroxide supplied from anodizing process of aluminum. In this manner, fluorine gas is treated while saving the quantity of amorphous aluminum hydroxide used and thus being free from industrial restriction.
