摘要：
An electrochemical method for producing F-18 sources for the slow positron beam was applied to the recovery of F-18 from (H2O)-O-18 water. The F-18 of activities 150-227 mCi (5.55-8.40 GBq) was electro-deposited on a graphite rod and then emitted into pure water. The best result of the efficiency for the electro-deposition for 5 min was 97% and that for the electro-emission for 5 min was 89%. The (H2O)-O-18 water is expected to be reused much more easily by this method than by the ion exchange resin method. The metal impurities contained in the F-18 solution were considerably reduced by using this method. (C) 2001 Elsevier Science Ltd. All rights reserved.
