ABSTRACT:
A method of treating a liquid effluent or groundwater containing organic contaminants is provided. The liquid effluent or groundwater containing the organic contaminants is contacted with hydrogen peroxide and transition metal ions. The hydrogen peroxide and transition metal ions are present in effective amounts based on the concentration of the organic contaminants in the liquid effluent or groundwater. The liquid effluent or groundwater is then irradiated with UV light having a poly- chromatic output between about 200 to 400 nm to decompose the organic contaminants. The ratio of hydrogen peroxide to transition metal ions is selected so as to favor the absorption of UV light by the hydrogen peroxide in the irradiation step.
