    Abstract: A method of destructing a toxic chemical, comprising the steps of mixing said toxic chemical with a liquid phase formed by an aqueous mixture of water and an ionic liquid or molten salt which is miscible with water, said ionic liquid or molten salt comprising a tertiary amine group or quaternary ammonium group; and contacting said toxic chemical in said liquid phase with said ionic liquid or molten salt so as to decompose said toxic chemical. The ionic liquid or molten salt comprises a tertiary amine group or quaternary ammonium group. The dispersion or solution further contains at least one oxidizing agent and a donor of hydrogen bonds. Decontamination of contaminated surfaces and decomposition of toxic substances are achieved by using environmentally friendly, non-toxic solvents and reactants which yields reaction products which are substantially non-harmful or even non-toxic.

    Abstract: There is described a process for treatment of a fluid comprising an oxidizable contaminant. The process comprises the step of contacting the wastewater with a combination of: (i) a sulfide, (ii) a complex of Fe(III) and a chelating agent, and (iii) an oxidant. It has been discovered that of treatment of a fluid containing an oxidizable contaminant employing iron(III)-chelates as the Fenton catalyst may be significantly improved by including a sulfide in the reaction scheme. As described herein, by employing sulfide ion, the present inventors have been able to: (i) increase the rate of iron recycling from minutes or hours to a few seconds, and (ii) destroy benzene in an oil and gas refinery (OGR) wastewater in less than one minute. It is believed that these findings in OGR wastewater can be extended to other fluids containing other oxidizable contaminants.
