A Novel Microporous Vanadosilicate with Hexadeca-Coordinated Cs+ Ions as a Highly Effective Cs+ Remover |
| 초록 |
The effective removal of 137Cs+ ions from contaminated groundwater and seawater and from radioactive nuclear waste solutions is crucial for public health and for the continuous operation of nuclear power plants. Various 137Cs+ removers have been developed, but more effective 137Cs+ removers are still needed. We recently reported a novel microporous vanadosilicate with mixed-valence vanadium (V4+ and V5+) ions, which shows an excellent ability for Cs+ capture and immobilization from groundwater, seawater, and nuclear waste solutions (Angew. Chem. Int. Ed. 2014, 53, 7203-7208). This material is superior to other known materials in terms of selectivity, capacity, and kinetics, and at very low Cs+ concentrations, it was found to be the most effective material for the removal of radioactive Cs+ ions under the test conditions. This novel vanadosilicate also contains hexadeca-coordinated Cs+ ions, which corresponds to the highest coordination number ever described. We will also present the properties of the related materials. |
