Abstract
Methods of detoxifying chemical warfare agents and decontaminating surfaces which have been exposed to chemical warfare agents are disclosed. The methods include contacting a composition confining a chemical warfare agent or contaminated surface with a sufficient amount of a sorbent which contains an activated aluminum oxide for a sufficient time and under conditions which are sufficient to produce a reaction product which is less toxic than the chemical warfare agent and/or to reduce the contamination of the surface by the chemical warfare agent.
Claims30
A method of detoxifying chemical warfare agents in situ which comprises applying a coating of a sorbent comprising aluminum oxide onto a composition comprising a chemical warfare agent and allowing the coating to react with the chemical warfare agent for a sufficient time and under conditions which are sufficient to produce a reaction product having less toxicity than the chemical warfare agent.
A method of decontaminating a surface which has been exposed to a chemical warfare agent which comprises contacting said surface with a sufficient amount of an activated aluminum oxide for a sufficient time and under conditions which are sufficient to reduce the contamination of said surface by said chemical warfare agent.
