Summary: | In this study, a simple electrochemical procedure adaptable for using low specific activity
W for separation and purification of
Re from
W to obtain no carrier added (NCA)
Re is developed. The electrochemical parameters were optimized to maximize the
Re electrodeposition yield with minimal
W contamination. Two cycle electrolysis procedure was developed. The first electrochemical cell was used for separation of
Re and in the second electrochemical cell, separation and purification of
Re with >90% deposition yield of
Re and minimal contamination of
W (90% with >99% radionuclidic purity and >99% radiochemical purity suitable for radiopharmaceutical applications. Furthermore, the performance of the generator remained consistent during a period of 69 days, one half-life of
W, when the electrochemical separation procedure was performed frequently, at least once in 5 days. |
