Abstract
A chemical solution and process for the decontamination of chemical warfare agents. More particularly, a process for the decontamination of the vesicant HD by oxidation to its corresponding sulfoxide and nerve agents VX and GD by perhydrolysis to their non-toxic phosphonic acids using environmentally safe reactants, specifically a citrate/bicarbonate/molybdate peroxide solution.
Claims21
A process for decontaminating a chemical warfare agent, comprising:
- contacting the chemical warfare agent with a liquid decontamination solution, the decontamination solution comprising a mixture of a potassium citrate salt, a carbonate component, potassium molybdate and a peroxide component, wherein the carbonate component comprises at least one member selected from the group consisting of carbonate and bicarbonate, and wherein said potassium citrate salt increases the stability of the decontamination solution.
