Abstract

An ozone storage apparatus for storing ozone efficiently and extracting ozone effectively is disclosed. Also ozone storage methods comprising the steps of supplying ozone either to a dried silica gel which is produced by neutralizing sodium silicate and sulfuric acid and that is then washed with water to a pH level between 6 and 7 or further processing the dried silica gel by crushing it and washing with at least one of a sulfuric acid or water. The methods also include a process where if oxygen has been adsorbed in the silica gel, a vacuum is created inside the storage container holding the silica gel, and then ozone can be supplied to the silica gel. Silica gel containing aluminum between 0.002-0.1 percent by weight is used for the storage medium. Also, the ozone is extracted from a tube-valve associated with the storage container by a natural downward flow.
