In this work the degradation of a model odor compound (dimethyl disulfide, DMDS) using Fenton's reaction is reported. Dimethyl disulfide is present in wastewaters generated during production of poultry feather and viscera meal. Oxidation was carried out in batch reactor with temperature control. Experimental design technique was used to investigate the influence of concentration of hydrogen peroxide and Fe(2+), temperature and pH on degradation of DMDS. Control reactions using H(2)O(2) without Fe(2+) were carried out, but DMDS degradation could only reach 60% for a 0.025 mg L(-1) DMDS solution, at pH 3, 60 degrees C using 10,000 mg L(-1) H(2)O(2) in 30 min of reaction. The Fenton's reaction could effectively remove DMDS, reaching 95% degradation at pH 3, 60 degrees C, 5 mg L(-1) H(2)O(2) and 1 mg L(-1) Fe(2+) after only 10 min of contact. A kinetic study of the Fenton's reaction was carried out, varying the concentration of hydrogen peroxide, Fe(2+) and temperature.
