| 摘要 |
A novel method of degrading, sequestering and/or immobilizing chemical contaminants in soil, sediment, or water is provided. The method comprises the addition of a sufficient amount of permanganate modified with a sufficient amount of an activator so as to destroy, sequester, and/or immobilize a detectable amount of the contaminants. In one aspect of the present invention, the permanganate and activator form a barrier or coating, composed of manganese oxides and components of the activator(s) that at least partially encapsulates a portion of the contaminant to minimize or prevent migration and/or dissolution of the contaminant. This encapsulation occurs via physical encrustation. The in situ remediation reagents of the present invention can be added to many contaminated environments including soil, sediment, rock, clay, water/groundwater and/or non-aqueous phase liquids.
