摘要

New threats emerged by various scenarios, which could create huge disasters by distributing agents of hazardous and toxic materials. These might be initiated by special warheads, storage bunkers in wars or war-like situations, asymmetric conflicts or even by terrorists. Therefore also infrastructural facilities like airport, railway or metro stations, city halls, storage houses etc. could be preferred targets to optimize the catastrophic result involving up to thousands of people. Assuming methods will be found to early detect and identify such substances or evolving events of distribution, an immediate response has to be initiated. Methods to expel anti-agents to burn, pyrolyze or neutralize aggressive chemical materials are discussed. Priority is given to the thermal destruction or oxidation of organic chemicals which are model substances of possible candidates to be used by B/C warfare and by terrorists. The results of theoretical calculations and experiments show that hydrogen/oxidizer mixtures, metal/oxidizer mixtures would be very effective to generate high temperatures which are needed for the destruction or at for least incapacitation. Spectroscopic measurements in the UV to the infrared spectral region confirmed the related high temperatures and intensity radiation of the burning mixture. Possibly, the oxide particles, when generated at a nano-scale, might support a photocatalytic mechanism of degradation of the organic materials.
