モリブデンのサイクルシステム及び当該サイクルシステムに使用されるモリブデン吸着剤の再生方法

摘要

PROBLEM TO BE SOLVED: To provide a cycle system of molybdenum for performing efficient collection of molybdenum at low cost and a method for regenerating molybdenum adsorbent to be used for the cycle system.SOLUTION: A cycle system of molybdenum includes the steps of: dissolving molybdenum or molybdenum trioxide containing molybdenum 99 to be adsorbed to molybdenum adsorbent; desorbing molybdenum existing in used molybdenum adsorbent after extracting technetium 99 m from a generator consisting of the molybdenum adsorbent; re-adsorbing molybdenum containing the molybdenum 99 to the molybdenum adsorbent after desorbing the molybdenum; and reusing the molybdenum trioxide to be collected in the desorption step. The regenerated molybdenum adsorbent after desorbing the molybdenum to be used in the re-adsorption step is preserved underwater, etc., and has at least one OH group in structure of a repetition unit.
