Abstract:
1. A method of treatment of a contaminate contaminated with an organic compound, comprising the steps of: (a) providing a contaminate, wherein the contaminate is contaminated with an organic compound; (b) treating the contaminate with a bioremediation step; wherein the bioremediation step comprises contacting the contaminate with a microbial consortium under conditions suitable for the microbial consortium to mediate solubilization or biodegradation of the organic compound or chemical oxidation products thereof; and (c) subsequently treating the contaminate with a chemical oxidation step; wherein the chemical oxidation step comprises: contacting the bioremediated contaminate with (i) a transition metal in soluble form; (ii) an isolated a chelator of the transition metal, wherein the chelator and the transition metal form a transition metal:chelator complex; (ii) an oxidizing agent that provides a reactive free radical in the presence of the complex; and (iv) a buffering salt to maintain the pH in the neutral range; wherein the reactive free radical initiates a chemical reaction with the organic compound to produce reaction products of the organic compound.
