1. A method of purifying used O-18 enriched cyclotron target water contaminated by various organic compounds, the method comprising:
- supplying continuously and directly gaseous oxygen into the target water to be purified;
irradiating UV rays having wavelengths of 254 nm and 185 nm on the target water; and
releasing gases generated during a purification process by oxidation,wherein, in the supplying gaseous oxygen, the gaseous oxygen is supplied by bubbling into the target water.

7. An apparatus for purifying used O-18 enriched cyclotron target water contaminated by various organic compounds, the apparatus comprising:
-
a reservoir for containing the target water; a UV irradiator for irradiating UV rays on the target water transferred from the reservoir; a heat exchanger for cooling the target water of a high temperature, transferred from the UV irradiator; a spectroscopic part for measuring concentration of organic impurities in the target water transferred from the UV irradiator; and a peristaltic pump for circulating the target water, wherein the apparatus is configured to allow the target water in a tube to receive gaseous oxygen continuously and directly into the reservoir, flow out from the reservoir through the UV irradiator, the heat exchanger, and the spectroscopic part, and flow into the reservoir again, and to allow the gaseous oxygen to bubble into the target water. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
