Item Aplicação de fotocatálise heterogênea e homogênea para a remoção de cor em efluentes provenientes de indústria de procesamento de couro(2014-08) Teran, Francisco Javier CubaThe purpose of this work was to study the effects of the application of advanced oxidative processes (POAs) to the removal of dyes in tanning industries effluents. Heterogeneous and homogeneus photocatalysis were tested applying glass-immobilized TiO2 with UV radiation (254 nm) and suspended H2 O2 also with UV radiation, respectively in order to obtain comparative results. Heterogeneus photocatalysys showed to be ineffective for dye removal. On the other hand, homogeneus photocatalysis with H2 O2 presented satisfactory results with 96 % removal in absorbance, 53% removal of organic load and 93% removal of total solids
