Contaminant Adsorption And Oxidation Via The Fenton Reaction
US Patent:
6663781, Dec 16, 2003
Filed:
Aug 28, 2000
Appl. No.:
09/649816
Inventors:
Scott G. Huling - Ada OK
Robert G. Arnold - Tucson AZ
Raymond A. Sierka - Tucson AZ
Robert G. Arnold - Tucson AZ
Raymond A. Sierka - Tucson AZ
Assignee:

International Classification:
C02F 128
US Classification:
210668, 210673, 210679, 210694, 210747
Abstract:
Contaminated water is treated by adsorbing contaminant onto a sorbent to concentrate the contaminant and then oxidizing the contaminant via the Fenton and related reactions. Iron is attached to the sorbent or can be added in solution with an oxidant. Both systems, iron attached to the sorbent or iron in solution, can be used to oxidize contaminants on or near the surface of the sorbent. The process can be used to treat contaminated water in above-ground and below-ground treatment systems.

Abstract:
Contaminated fluids are treated by adsorbing contaminant onto a sorbent to concentrate the contaminant and then oxidizing the contaminant via the Fenton and related reactions. Iron is attached to the sorbent or can be added in solution with an oxidant. Both systems, iron attached to the sorbent or iron in solution, can be used to oxidize contaminants on or near the surface of the sorbent. The process can be used to treat contaminated water in above-ground and below-ground treatment systems, as well as contaminated gases.
