Manganese-mediated redox processes for environmental contaminant remediation

Abstract

Methods and compositions for the remediation of environmental contaminants using redox reactions are described. The redox reactions include manganese compounds and peroxide generating compounds. The methods and compositions are also useful for the remediation of highly oxidized environmental contaminants.

         29 . A kit comprising a permanganate, a phosphate buffer, and a peroxide or a compound capable of forming a peroxide, and a set of instructions for using the kit for remediation of a site having one or more soil contaminants, one or more groundwater contaminants, or a combination thereof. 
     
     
         30 . The kit of  claim 29  wherein the phosphate buffer and the peroxide or the compound capable of forming a peroxide are included in a ratio in the range from about 1:1 to about 10:1. 
     
     
         31 . The kit of  claim 29  wherein the phosphate buffer and the peroxide or the compound capable of forming a peroxide are premixed at a ratio in the range from about 1:1 to about 10:1. 
     
     
         32 . The kit of  claim 29  further comprising a pH modifying agent capable of increasing the pH of the site. 
     
     
         33 . The kit of  claim 32  wherein the pH modifying agent is selected from the group consisting of NaOH, KOH, Na 3 PO 4 , K 3 PO 4 , KH 2 PO 4 , K 2 HPO 4 , and combinations thereof.
