Título alternativo:Effect of the addition of persulfate or H2O2 on the degradation of phenol by ce-doped TiO2
Resumen
Degradation of phenol was used as a model reaction to investigate the photocatalytic properties of cerium-doped (0.1% atomic nominal) TiO2 catalyst, in the absence and presence of oxidants: persulphate (PS) or hydrogen peroxide (H2O2). Parallel experiments have been performed using either artificial ultraviolet and visible light or sunlight during spring-summer seasons in La Plata city (34.90°S, 57.92°W, 15masl) in a batch reactor. The best result was found with doped material and 7.0mM of PS: total mineralization (250μM phenol) after 5 hours of solar exposition. Different intermediates were identified for the studied treatments.
