POROUS IRON OXIDE, PROCESS FOR PRODUCING THE SAME, AND METHOD OF TREATING WATER |
摘要 |
<p>To provide a recovery agent for recovering arsenic, fluorine, lead, and selenium from a solution containing environmentally hazardous substances including arsenic and fluorine. A porous iron oxide having a particle size of 10 to 100µm and a specific surface area of 50m 2 /g or larger determined by three-point BET method is introduced into a solution containing the environmentally hazardous substances. Alternatively, a solution containing the environmentally hazardous substances is passed through a column filled with the porous iron oxide. Thus, the environmentally hazardous substances are recovered from the solution.</p> |
