Abstract: A filtration system and method for the remediation of hydrazine from contaminated gas is disclosed. The system is provided in the form of a container with an net port and an outlet port containing absorbent pads or filters or wipes saturated with a solution of a dicarbonyl compound. As contaminated gas passes through the container, hydrazine present within the gas reacts with the dicarbonyl compound and becomes neutralized, thereby resulting in the exit of pure gas that no longer contains hydrazine from the container. The system can remediate hydrazine from ammonia borane to efficiently regenerate spent said ammonia borane from polyborazylene as a hydrogen storage material. The absorbent pads can also be used independently to remove hydrazine liquid spill.

Abstract: An air filtration system and method for the remediation of hydrazine from contaminated air. The system is provided in the form of a container with an inlet port and an outlet port containing absorbent pads or filters or wipes saturated with a solution of a dicarbonyl compound. As contaminated air passes through the container, hydrazine present within the air reacts with the dicarbonyl compound and becomes neutralized, thereby resulting in the exit of pure air from the container. The absorbent pads can also be used independently to remove hydrazine liquid spill.

Abstract: An apparatus for remediating hydrazine and a method of manufacturing the apparatus for remediating hydrazine are disclosed. A pad treated with a dicarbonyl compound can be utilized to remediate hydrazine spills or hydrazine-contaminated surfaces. The apparatus to remediate hydrazine includes a pad comprising an absorbent medium pre-treated with a dicarbonyl compound, wherein a solution, surface, device, or component contaminated with hydrazine reacts with the dicarbonyl compound of the pad to convert the hydrazine into a stable organic compound, thereby decontaminating the spill. The pad may include a porous surface cover surrounding an inert absorbent medium component that in turn supports a dicarbonyl compound that reacts with the hydrazine from the surface. The absorbent medium can be a pad, fibrous material, granular material, or an aqueous absorbent medium. The absorbent medium generally comprises a porous outer fabric surface covering that allows solutions or vapors to pass into the pad's interior.

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.
