FIELD: chemistry.
SUBSTANCE: method for increasing ozone concentration in a liquid can include: providing a gas containing ozone; introducing the ozone-containing gas into a liquid, wherein the liquid and ozone combination is at temperature between about 0.8 and about 1.5 times the critical temperature of ozone; and increasing isothermally, the pressure of the ozone-containing gas above the liquid to about 0.3-5 times the critical pressure of ozone so as to increase ozone concentration in the liquid. The temperature is expressed in absolute units (Kelvin or Rankin). The method can be used to remove ozone from a gas or for purifying ozone.
EFFECT: more efficient ozone purification.
