The photo- Fenton process was evaluated for the treatment of two effluents (A and B) from ink industry. The influence of hydrogen peroxide and iron (II) concentration on the dissolved organic carbon (DOC) removal was evaluated. In the first minutes of irradiation the color and odors were removed. For the effluent A 75% of DOC removal was reached in 60 min irradiation. For the effluent B, multiple additions of H2O2 were necessary to improve the COD removal, reaching 43% of TOC in 60 min irradiation. The results obtained demonstrate that the solar photo-Fenton process can be applied for the treatment of effluents generated by ink industry.
