| 研究開始時の研究の概要 |
It is extremely urgent to find an innovative technology that can efficiently and simultaneously remove these pollutants from contaminated water. Conclusively, three ‘’key scientific questions’’ are aimed to be answered here: 1) Can we develop a novel nanocomposite that can efficiently and simultaneously remove both HMs and RNs from contaminated water? 2) Will it be able to achieve the multi-mechanism concept to feasibly perform in the complex (waste)water? 3) Can it be utilized in real water treatment applications?

| 研究実績の概要 |
Bi-, and tri-metallic iron nanoparticles showed good potential in simultaneous removal of heavy metals (Cr(VI) and As(V)) and radionuclides (U and Re).
- Carbon nano-onions (CNOs) were prepared using hydrothermal pyrolysis of citric acid and chitosan. However, the satisfactory level of the morphology of the prepared carbon-based materials needs to be enhanced.

2: おおむね順調に進展している
理由
- The yield rate, purity, and morphology of carbon nano-onions (CNOs) from hydrothermal pyrolysis approach were not as expected.
|
| 今後の研究の推進方策 |
- CNOs will be prepared by high-temperature annealing of detonated nanodomains.
- The incorporation of the carbon-metal nanohybrids into polymeric membrane will be conducted after investigating the characteristics of the developed composites.
