| Outline of Final Research Achievements |
We tested Caesium, Strontium(Sr) and some other alkaline or alkaline earth ion uptake by Metal-Organic-Frameworks(MOF) with the formula of (NH4)[Ln(C2O4) 2 (H2O)] (Ln = Y, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb) to apply it for removing and recovering radioactive elements. According to the results, the selectivity of metal changed with the change of host lanthanide ions in MOFs and (NH4)[Ln(C2O4) 2 (H2O)] has high selectivity to Sr even in sea water. And we also succeeded recovery of these guest ions from the MOF. From these results, we made a new promising adsorbent for removing and recovering radioactive waste from radioactive waste solution.
