Abstract
Official abstract text for this publication.
Various embodiments of contaminant removal systems, compositions, and methods are described herein. In one embodiment, a method for oxidizing a contaminant includes contacting the contaminant with a peroxygen compound and initializing, maintaining, or propagating degradation of the peroxygen compound with an oxygenated organic compound, thereby releasing oxidizing radicals. The method also includes oxidizing the contaminant with the released oxidizing radicals.
First claim
Opening claim text (preview).
We claim: 1. A method for oxidizing a contaminant present in a medium including sediment, soil, rock groundwater, wastewater, or process water, the method comprising: contacting the contaminant in the medium with a persulfate salt; activating decomposition of the persulfate salt with at least one of glucose, fructose, lactose, or galactose; decomposing the persulfate salt to release sulfate radicals as follows: − O 3 S—O—O—SO 3 − →SO 4 •− +SO 4 2− ; and oxidizi…
