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.

1 - 85 . (canceled) 
     
     
         86 . A method of reducing the concentration of an organic compound in contaminated material, the method comprising:
 introducing an oligosaccharide to the contaminated material;   introducing ozone to the contaminated material; and   forming a clathrate from the ozone and the oligosaccharide.   
     
     
         87 . The method of  claim 86  further comprising the step of introducing at least one oxidant in addition to the ozone to the contaminated material. 
     
     
         88 . The method of  claim 87  wherein the at least one oxidant comprises at least one of a persulfate compound, a permanganate compound, a percarbonate compound and a peroxide compound. 
     
     
         89 . The method of  claim 87  further comprising introducing an activator to the material. 
     
     
         90 . The method of  claim 86  wherein ozone is introduced to the contaminated material prior to introducing the oligosaccharide. 
     
     
         91 . The method of  claim 86  wherein the oligosaccharide is introduced to the contaminated material prior to introducing the ozone. 
     
     
         92 . The method of  claim 86  wherein the ozone and the oligosaccharide are simultaneously introduced to the contaminated material. 
     
     
         93 . The method of  claim 86  further comprising the step of oxidizing at least a portion of at least one organic contaminant present in the contaminated material. 
     
     
         94 . The method of  claim 86  wherein the ozone and the oligosaccharide are introduced to the contaminated material through different injection wells. 
     
     
         95 . The method of  claim 86  wherein the ozone and the oligosaccharide are introduced to the contaminated material through a common injection well. 
     
     
         96 . The method of  claim 86  further comprising altering a rate at which the ozone is released from the clathrate by altering the pH of a fluid comprising the clathrate. 
     
     
         97 . The method of  claim 86  further comprising desorbing or solubilizing an organic compound from the material with the clathrate. 
     
     
         98 . A method of reducing the concentration of an organic compound in contaminated material, the method comprising:
 forming a clathrate solution comprising an ozone and an oligosaccharide; and   introducing the clathrate solution to the contaminated material.   
     
     
         99 . The method of  claim 98  further comprising the step of introducing at least one oxidant in addition to the clathrate to the contaminated material. 
     
     
         100 . The method of  claim 99  wherein the at least one oxidant comprises at least one of a persulfate compound, a permanganate compound, a percarbonate compound and a peroxide compound. 
     
     
         101 . The method of  claim 99  further comprising introducing an activator to the material. 
     
     
         102 . The method of  claim 98  further comprising the step of oxidizing at least a portion of at least one organic contaminant present in the contaminated material. 
     
     
         103 . The method of  claim 98  further comprising altering a rate at which the ozone is released from the clathrate by altering the pH of a fluid comprising the clathrate. 
     
     
         104 . The method of  claim 98  wherein the clathrate is introduced to the contaminated material through an injection well. 
     
     
         105 . The method of  claim 98  further comprising desorbing or solubilizing an organic compound from the material with the clathrate.
