Outline of Final Research Achievements |
The porous iron oxide particles developed by novel liquid phase reaction process were applied to the hazardous chemical species removing and useful chemical species recovering from environmental or industrial water using adsorption-desorption system. As synthesized porous iron oxide particles did not have enough magnetic property for increasing the desorption efficiency due to the quite small particle size. We found out the effect of after heat treatment under reductive atmosphere on growth of the particle size and transition of iron oxide phase from maghemite to magnetite. It was confirmed that the heat treated particles generate heat and increase the water temperature. The adsorbent particles showed significant difference in the desorption efficiency of arsenic between under with and without applying an alternating magnetic field.
