Research Subject
Development of porous adsorbing materials to remove toxic elements from water

研究の背景 Background


For development of functional materials suitable for practical use, considering not only each physicochemical property but also the whole system using the materials is necessary. For example, for the particulate absorbent using to remove toxic chemical species from the water environment, the material requiring a large amount of treatment agents in desorption process is not suitable for use, even if it has high adsorption properties. Therefore, simplification and efficiency of the desorbing process is desired in order to establish the practical water treatment system. The clarification of relation between the properties and local structure is very important.

研究の目標 Outcome


The development of the magnetic iron oxide particles with large particle size, large specific surface area, and large pore and void volume as adsorbent material by using novel liquid phase reaction process has been investigated. The aim is establishment of a system with high efficiency in desorption and condensation recovery for the physical thermo-effect induced by applied alternating magnetic field. The optimization of void design, local structure and magnetic properties for suitable adsorbent material have been promoted as well as the progress of adsorption-desorption characteristics.
