| Outline of Final Research Achievements |
In this research, a variety of recovery materials were developed to construct a rare-metal recycle system for the used high-tech products by combination of the recovery materials. Melamine cyanurate was found to be a selective adsorbent for Pd(II) from a mixture of six metal ions. A high-recovery system was developed by complexation between trithiocyanuric acid (TCA) and melamine (Mel) through hydrogen bonding. The maximum recovery amount (1.248 gPd/gTCA-Mel) was greater than the previous reported materials. For the recovery of metals in organic solvents, a recovery system that involves homogeneous coordination during metal recovery and becomes heterogeneous for separation after recovery based on reversible association/dissociation between tetraamine and diol through hydrogen bonding. This system recovered Pd(II) or Cu(II) quantitatively.
