Hydrazine decontamination wipes

Abstract

An apparatus for remediating hydrazine from hydrazine contaminated surfaces. Pads or wipes can be utilized to remediate hydrazine spills. In its operational form, the dicarbonyl compound may be present on or in the absorbent material in a dry form or an aqueous solution. The apparatus includes a wipe comprising an absorbent medium pre-treated with a dicarbonyl compound, wherein the surface contaminated with hydrazine reacts with the dicarbonyl compound of the wipe to neutralize and convert the hydrazine into a stable organic compound, thereby decontaminating the surface. The wipe itself may include a porous surface cover surrounding an inert absorbent interior component of the wipe that in turn surrounds an absorbent interior core comprising a dicarbonyl compound that reacts with the hydrazine in order to neutralize the hydrazine on the surface. The absorbent medium generally comprises a porous outer fabric surface covering that draws the hydrazine on the surface to the wipe.

1 . An apparatus for remediating a surface contaminated with hydrazine, said apparatus comprising:
 a wipe comprising an absorbent medium pre-treated with a dicarbonyl compound, wherein said surface contaminated with hydrazine reacts with said dicarbonyl compound of said wipe to neutralize and convert said hydrazine into a decontaminated and stable organic compound, thereby decontaminating said surface.   
     
     
         2 . The apparatus of  claim 1  wherein said wipe comprises a porous surface cover surrounding an inert absorbent interior component of said wipe that in turn surrounds an absorbent interior core comprising a dicarbonyl compound that reacts with said hydrazine in order to neutralize said hydrazine on said surface. 
     
     
         3 . The apparatus of  claim 1  wherein said absorbent medium comprises a porous outer fabric surface covering that draws said hydrazine on said surface into said wipe. 
     
     
         4 . The apparatus of  claim 1  wherein said dicarbonyl compound comprises ketoglutaric acid. 
     
     
         5 . The apparatus of  claim 1  wherein said dicarbonyl compound comprises a beta-dicarbonyl compound.

         7 . The apparatus of  claim 1  wherein said dicarbonyl compound comprises a remote dicarbonyl compound. 
     
     
         8 . The apparatus of  claim 7  wherein said remote dicarbonyl compound comprises acetoacetone. 
     
     
         9 . The apparatus of  claim 7  wherein said remote dicarbonyl compound comprises propanedial. 
     
     
         10 . The apparatus of  claim 7  wherein said remote dicarbonyl compound comprises ethyl acetoacetate. 
     
     
         11 . The apparatus of  claim 7  wherein said remote dicarbonyl compound comprises levulinic acid. 
     
     
         12 . The apparatus of  claim 7  wherein said remote dicarbonyl compound comprises ethyl levulinate. 
     
     
         13 . The apparatus of  claim 7  wherein said remote dicarbonyl compound comprises 1,3-diphenylpropane-1,3-dione. 
     
     
         14 . The apparatus of  claim 1  wherein said dicarbonyl compound comprises a compound selected from a carbonyl-like functional group. 
     
     
         15 . The apparatus of  claim 1  wherein said dicarbonyl compound selected from a carbonyl-like functional group comprises acetoacetonitrile. 
     
     
         16 . The apparatus of  claim 1  wherein said dicarbonyl compound comprises a dry material. 
     
     
         17 . The apparatus of  claim 1  wherein said dicarbonyl compound comprises an aerosol. 
     
     
         18 . The apparatus of  claim 1  wherein said absorbent medium comprises an aqueous absorbent medium. 
     
     
         19 . The apparatus of  claim 1  wherein said wipe comprises synthetic fibers.
