A separating and collecting method for collecting high-purity 18F from 18O water with high efficiency and maintaining the purity of the 18O water. By using a solid electrode (1) as an anode and a container (electrodeposition bath) (2) made of platinum as a cathode, 18F in a solution (4) is electrodeposited on the solid electrode by applying a voltage. Then by using the solid electrode (1) on which 18F is electrodeposited as a cathode and a container (collecting bath) (5) in which pure water is placed as an anode, 18F is collected in the pure water by applying a voltage of the opposite polarity to that of the electrodeposition. In the process, the loss of the 18O water is little. The initial concentration of the 18O water is maintained even after the 18F electrodeposition, and therefore the 18O water can be repeatedly used as an irradiation target for production of 18F.

Cette invention concerne une méthode de séparation et de collecte de ?18¿F d'une grande pureté à partir d'eau ?18¿O, ceci avec une grande efficacité et sans compromettre la pureté de l'eau ?18¿O. L'emploi d'une électrode solide (1) comme anode et d'un récipient (bain d'électrodéposition) (2) de platine comme cathode permet, par application d'une tension, de réaliser une électrodéposition de ?18¿F en solution sur l'électrode solide. Ensuite, en utilisant l'électrode solide (1) sur laquelle s'est déposé ?18¿F comme cathode ainsi qu'un récipient (bain collecteur) (5) rempli d'eau pure comme anode, on recueille ?18¿F dans l'eau pure en appliquant une tension de polarité opposée à celle utilisée pour l'électrodéposition. Ce procédé n'entraîne qu'une faible perte d'eau ?18¿O. La concentration initiale d'eau ?18¿O est maintenue même après électrodéposition de ?18¿F. Dans ces conditions, l'eau ?18¿O peut être utilisée de façon répétée comme cible d'irradiation pour la production de ?18¿F.
