Abstract
The present invention relates generally to the destruction of chemical weapons. In particular, the present invention relates to methods for treating hydrolysates of chemical agents. In one embodiment, the present invention provides a method comprising oxidizing a hydrolysate of a chemical agent to produce an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration, and separating the organic layer from the aqueous layer.
Claims26
A method of treating a hydrolysate of a chemical agent, comprising:
- oxidizing a hydrolysate of a chemical agent to form an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration;
- and
- separating the organic layer from the aqueous layer.
A method of treating a hydrolysate of a chemical agent, comprising:
- oxidizing the hydrolysate of a chemical agent to form an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration;
- separating the organic layer from the aqueous layer;
- removing the organophosphorus concentration from the aqueous layer;
- and
- removing the organosulfur concentration from the organic layer.
A method of treating a hydrolysate of a chemical agent, comprising:
- oxidizing a hydrolysate of a chemical agent to form an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration, and oxidizing and precipitating the organophosphorus concentration from the aqueous layer.
A method of treating a hydrolysate of a chemical agent, comprising:
- oxidizing an organophosphorus concentration of a chemical agent hydrolysate solution, comprising contacting the organophosphorus concentration with an oxidizing agent, a metal catalyst selected from iron, magnesium, and combinations of these, and optional pH adjusting chemical species;
- and
- precipitating the oxidized organophosphorus concentration from the hydrolysate solution.
A method for destroying chemical agents capable of use as chemical weapons comprising
- oxidizing a hydrolysate of a chemical agent to form an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration;
- and
- separating the organic layer from the aqueous layer.
