| The heterogeneous photocatalysis constitutes an efficient alternative for the treatment of wastewaters polluted with toxic and recalcitrant substances . In this work the characteriz ation of TiO 2 nanomaterial obtained by an electrolytic procedure, and its evaluation to degr ade paracetamol in aqueous solution are presented . The characterization with X rays diffraction, Fourier transform infrared spectroscopy and energy dispersive X ray spectroscopy, evidenced the obtaining of the material. The particle size, determined by tra nsmission electron microscopy, was 9.3 nm ± 2.7 nm and the surface area was 115,4 m 2 /g according to the Brunauer Emmett Teller isotherm. The resulting optical band gap of the sample, determined by diffuse reflectance spectroscopy, was 3.15 eV (393 nm). The obtained nanoparticles were tested in the photodecomposition of paracetamol. Approximately 60% of pollutant was degraded with sun light, an d 76% with artificial UV light. |
