CA 2075511

A method for mineralizing pesticides, notably aromatic pesticides, using ferric ion in an acid aqueous solution at room temperature is disclosed. In a preferred embodiment, the ferric ion is employed in the presence of hydrogen peroxide; degradation occurs in the light or in the dark, although light accelerates the degradation. The method also is functional in the absence of hydrogen peroxide, but light and oxygen is required in this method. Preferred degradation methods are conducted in the presence of hydrogen peroxide and light, and in the absence of large concentrations of organic solvents, chloride, and sulfate.
