| Outline of Final Research Achievements |
Stable supply of dysprosium (Dy) is one of the major problems in the automotive industry due to the increase in Dy consumption and low volume production. Therefore, investigations on new recycling methods are extremely demanding. We focused on mesoporous silica particles (MPS) that have tunable nanoscaled mesopores. The silica materials were treated via amino functionalization by replacing silane coupling reagents, 3-aminopropyltriethoxysilane, N-(2-aminoethyl)-3-aminopropyltriethoxysilane, and N-(6-aminohexyl)-3-aminopropyltrimethoxysilane, as well as via carboxyl functionalization using diglycolic acid, respectively. Selective Dy ions adsorption from several metal ions in the solutions was performed using these materials. Interestingly, MPS sheet-2HNHCOOH having sheet likes morphologies presented the enhanced Dy ions adsorption. The results suggested that the MPS sheet-2HNHCOOH was a candidate material for the selective Dy ions adsorption.
