Oxidative Decontamination

Objectives:Develop a non-corrosive, material compatible, non-toxic and environmentally friendly oxidative chemical and biological decontaminant to replace DS2 and STB/HTH for thorough decon.

Payoffs:� Neutralization of CWAs at material-

friendly pH of 7.5-9.0 by either oxidation or displacement reactions yielding acceptable reaction products.

� Decontaminant will be effective against all CB agents.

� Uses formulation approach � allows incorporation of enzymes and polymeric catalysts (DTO CB.09) and DARPA developed bio decon formulation.

� Uses simple in-situ mixing and is compatible with existing decon applicators.

Edgewood Chemical Biological Center

� Additives to improve reactivity� Activators� Commercial catalysts� Improved solvents

� Liquid or solid concentrates (leveraging off of commercial formulation industry)� Freeze dried or stabilized enzyme solutions � Mixed formulations (similar to laundry detergents)

� Efficient applicator systems to prevent waste� Foam application � increases contact time, minimizes run off� Dual use mixer/applicator� Spray on / vacuum off systems

Solution Chemistry Technical Requirements

Edgewood Chemical Biological Center

� Materials compatibility information� Comprehensive database of aircraft interior

materials of construction� Safety-of-flight components � aircraft wiring,

hydraulic seals, POL, etc.� Better understanding of unique shaded/hidden

areas, complex geometries and interior airflow characteristics

� Material friendly decontaminants

JSSED Technical Requirements

Edgewood Chemical Biological Center

� Supercritical carbon dioxide (SCCO2)� HD and GB are highly soluble� HD and GB are effectively removed from various materials and

complex shapes� VX and TGD testing underway

� Non-Ozone Depleting Solvent Wash System� Pseudo �dishwasher� design with

the ability to filter and recycle thesolvent

� Exploring the use of reactivenanoparticles as an in-linefiltration system for the solvent
