METHOD FOR SEPARATING AND COLLECTING ?18 F IN ?18 O WATER

摘要

A method of separating and recovering <18>F from <18>O water at high purity and efficiency while maintaining the purity of the <18>O water. By using a solid electrode (1) as an anode and a container (electrodeposition vessel) (2) made of platinum as a cathode, <18>F in a solution (4) is electrodeposited on the solid electrode surface by applying a voltage. Then, by using the solid electrode (1) on which <18>F is electrodeposited as a cathode and a container (recovery vessel) (5) holding pure water therein as an anode, <18>F is recovered in the pure water by applying a voltage of opposite polarity to that of the electrodeposition. In this process, little <18>O water is lost. The initial concentration of the <18>O water is maintained even after the electrodeposition of <18>F, so that the <18>O water can be repeatedly used as an irradiation target for production of <18>F. <IMAGE>
