Abstract
Applicability of newly developed PZC (poly zirconium compound) to an adsorbent for a188W/188Re generator system was investigated for long term. The PZC generator gave reproducible 188Re elution yields (60-75%) with 0.03% of 188W parent breakthrough during 154 days corresponding to twice of the half-life of 188W (69.4 d). Furthermore, the labeling yields of hydroxyethyliden diphosphonic acid and mercaptoacetyltriglycine with 188Re eluted from the PZC column were high enough and there was no significant different with the results using 188Re eluted from the alumina system. The 188W/188Re generator prepared by PZC indicated a good performance for the practical use.
