Chemical Oxidation Method and Compounds

Abstract

A method and system for the reduction of contamination in soil and groundwater is provided. Cyclic oligosaccharides can be used, for example, to carry oxidants, carry activators, solubilize organic contaminants and promote biodegradation.

What is claimed is: 
     
         1 . A method of reducing the concentration of an organic compound in a contaminated material, the method comprising:
 forming a clathrate comprising ozone and a cyclic oligosaccharide; and   introducing the clathrate to the contaminated material.   
     
     
         2 . The method of  claim 1  further comprising the step of introducing at least one oxidant in addition to the ozone to the contaminated material. 
     
     
         3 . The method of  claim 2  wherein the at least one oxidant comprises at least one of a persulfate compound, a permanganate compound, a percarbonate compound and a peroxide compound. 
     
     
         4 . The method of  claim 2  further comprising introducing an activator to the contaminated material. 
     
     
         5 . The method of  claim 1  further comprising the step of oxidizing at least a portion of at least one organic contaminant present in the contaminated material. 
     
     
         6 . The method of  claim 1  further comprising altering a rate at which the ozone is released from the clathrate by altering the pH of a fluid comprising the clathrate. 
     
     
         7 . The method of  claim 1  further comprising desorbing or solubilizing an organic compound from the contaminated material with the clathrate. 
     
     
         8 . The method of  claim 1  wherein the cyclic oligosaccharide is cyclodextrin. 
     
     
         9 . A method of reducing the concentration of an organic compound in a contaminated material, the method comprising:
 forming a clathrate solution comprising ozone and a cyclic oligosaccharide;   introducing the clathrate solution to the contaminated material; and   introducing at least one oxidant in addition to the clathrate to the contaminated material.   
     
     
         10 . The method of  claim 9  wherein the at least one oxidant comprises at least one of a persulfate compound, a permanganate compound, a percarbonate compound and a peroxide compound. 
     
     
         11 . The method of  claim 9  further comprising introducing an activator to the contaminated material. 
     
     
         12 . The method of  claim 9  further comprising the step of oxidizing at least a portion of at least one organic contaminant present in the contaminated material. 
     
     
         13 . The method of  claim 9  further comprising altering a rate at which the ozone is released from the clathrate by altering the pH of a fluid comprising the clathrate. 
     
     
         14 . The method of  claim 9  wherein the clathrate is introduced to the contaminated material through an injection well. 
     
     
         15 . The method of  claim 9  further comprising desorbing or solubilizing an organic compound from the contaminated material with the clathrate. 
     
     
         16 . The method of  claim 9  wherein the cyclic oligosaccharide is cyclodextrin.
