Its use produces waste which must be treated before being discharged into rivers or sewage. Combined processes have been used with efficiency for wastewater treatment. This study aims to evaluate the combined process of photo-Fenton and adsorption for the degradation and removal of the dye CBB in aqueous solution. Initially, the CBB was submitted to photo-Fenton oxidation. Photo-Fenton oxidation degraded 76,9% of the initial CBB concentration, which was not enough to satisfies the Brazilian legislation. The fixedbed adsorption was conducted for 13 hours, and during all this period the outlet concentration was always lower than the breakpoint, being this concentration in compliance with the legislation. The combined photo-Fenton/Fixed-bed adsorption was effective in the CBB removing (at least 95,9%).
