<p>The present invention relates to the use of heterogeneous photocatalysis for eliminating Bentazon (3-isopropyl-2,1,3-benzothiadiazinon-(4)-2,2-dioxide) from fresh waters. Exposing aqueous solutions of bentazon (50 ppm) to light radiations of wavelengths >/=340 nm, for instance irradiations generated from an illumination source with a spectral distribution that simulates AM1 solar radiation, in the presence of titanium dioxide, the complete mineralization of pollutant herbicide is obtained quickly.</p> |
