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.
