Abstract

A method of concentrating ozone gas in which, although the apparatus configuration is simple, ozone gas of a predetermined concentration can be efficiently taken out, and an apparatus therefor are provided. In a method of concentrating ozone gas in which an ozone-oxygen mixture gas is acted in an adsorbing column that is filled with an adsorbent, to cause the adsorbent to selectively adsorb the ozone gas, and the selectively adsorbed ozone gas is desorbed, thereby concentrating and purifying the ozone gas, the ozone-oxygen mixture gas is acted on the adsorbent in a non-cooled state to cause the ozone gas to be selectively adsorbed to the adsorbent, the adsorbing column is vacuumed when performing an operation desorbing of the ozone gas, thereby desorbing the ozone gas from the adsorbent, and an initial amount of the leading out of the desorbed ozone gas is not recovered, thereby obtaining high-concentration ozone gas.
