Abstract
A sequential process is provided for the destruction of a toxic organic chlorine-containing compound, especially a chlorine- and arsenic-containing compound e.g., a Lewisite or a mustard gas. The process includes the first step of carrying out an oxidizing reaction between the chlorine-containing compound, and an oxidizing agent, especially hydrogen peroxide, while maintaining the temperature and the pH within preselected ranges e.g., about 50.degree. C. to about 90.degree. C. and the pH starting at about 1 to about 2 during the oxidation and terminating at about 5 to about 8 to provide an oxidation product of the original toxic organic chlorine-containing compound, original toxic chlorine- and arsenic-containing compound. After completion of the oxidizing reaction, any residual oxidizing agent is preferably catalytically decomposed. Then, the oxidation product of the original toxic organic chlorine-containing compound, is decomposed at an alkaline pH, e.g., to a maximum final pH of about 11 to provide an inorganic compound, e.g., an inorganic arsenic-containing compound. Such compound can easily and safely be disposed of.
