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.
