Reactive compositions containing superoxide ion for the degradation of halogenated organic compounds
Abstract
Reagent compositions suitable for use in degrading and detoxifying polyhalogenated organic compounds comprising an aprotic solvent having dissolved therein (a) an effective amount of hydrogen donor, (b) an effective amount of a compound which produces hydroxide ion or alkoxide ion, and (c) dioxygen, are shown. These reagent compositions may be used to produce superoxide ion in situ for use in a variety of industrial applications to degrade halogenated hydrocarbons, e.g., PCBs. The generation of superoxide ion may be catalyzed by the presence of anthraquinone and derivatives thereof. Reagent compositions containing (a) an effective amount of hydrogen donor, e.g., hydroxylamine, (b) an effective amount of a compound which produces hydroxide ion or alkoxide ion and (c) dioxygen are also shown. In preferred methods the dioxygen is bubbled through the solutions to continuously form superoxide ion.
