MANGANESE DIOXIDE HEAVY METAL ADSORBENT AND TREATMENT METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heavy metal adsorbent containing, as an active ingredient, a new manganese dioxide excellent in the adsorption character of heavy metals, and a method which detoxifies incinerated ashes, fly ashes, molten fly ashes, waste, waste water, and soil, which contain various heavy metals, by using the heavy metal adsorbent.;SOLUTION: The heavy metal adsorbent contains the manganese dioxide in which a weight reduction in a temperature rise starting from 120°C up to 400°C is 6 wt.% or more, as an active ingredient. The concerned heavy metal adsorbent is added to any one of the garbage incineration ashes, the fly ashes, or the molten fly ashes containing the heavy metals, or to the soil and the waste water containing the heavy metals. By kneading them, the heavy metals can be detoxified.;COPYRIGHT: (C)2008,JPO&INPIT
