Abstract
A method of purifying the used O-18 enriched cyclotron target water contaminated by the various organic compounds, the method including: supplying 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 the gases generated during the purification oxidation process.

A method of purifying the used O-18 enriched cyclotron target water contaminated by the various organic compounds, the method comprising:
- supplying 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 the gases generated during the purification process by oxidation.
An apparatus for purifying the used O-18 enriched cyclotron target water contaminated by the various organic compounds, the apparatus comprising:
- a reservoir for containing the target water;
- a UV irradiator irradiating UV rays on the target water transferred from the reservoir;
- a heat exchanger cooling the target water of a high temperature, transferred from the UV irradiator;
- a spectroscopic part measuring concentration of the organic impurities in the target water transferred from the UV irradiator;
- and
- a peristaltic pump circulating the target water,
- wherein the target water in a tube receives gaseous oxygen in the reservoir, flows out from the reservoir through the UV irradiator, the heat exchanger, and the spectroscopic part, and flows into the reservoir again.
