The degradation of wheat straw black liquor (WSBL) by using Fenton's reagent is investigated. Also, the use of irradiation providing the conditions needed for the occurrence of photo-Fenton's reaction, along with the main parameters that govern the complex reactive system have been studied. Concentrations of Fe(II) between 20 and 1,000 ppm, and H2O 2 between 500 and 2,000 ppm were chosen. The best results were obtained when using 1,500 ppm H2O2 and 200 ppm Fe(II) [12:1 molar ratio of H2O2/Fe(II)]. The use of Fenton's and photo-Fenton's reactions has been proven to be highly effective for the treatment of such a type of wastewaters; and accordingly, the high levels of chemical oxygen demand (COD), aromatic content (UV254), and lignin content (UV280) removal. © Mary Ann Liebert, Inc. 2008.
