Abstract	The oil and petrochemical industry is responsable t o generate a large amount of waste and wastewater. Among some efluents, is possible fi nd the benzene, toluene, ethilbenze and isomers of xilenes compounds, known as BTEX. These compounds are very volatily, toxic for environment and potencially cancerigenous in man. O xidative advanced processes, OAP, are unconventional waste treatment, wich may be apply o n treatment and remotion this compounds. Fenton is a type of OAPs, wich uses the Fenton’s reactant, hydrogen peroxide and ferrous salt, to promove the organic degradatio n. While the Photo-Fenton type uses the Fenton’s reactant plus UV radiation (ultraviolet). These two types of OAP, according to literature, may be apply on BTEX complex system. Th is project consists on the consideration of the utilization of technologies Fenton and Photo -Fenton in aqueous solution in concentration of 100 ppm of BTEX, each, on simulati on of condition near of petrochemical effluents. Different reactors were used for each ty pe of OAP. For the analyticals results of amount of remotion were used the SPME technique (so lid phase microextraction) for extraction in gaseous phase of these analytes and t he gas chromatography/mass espectrometry The arrangement mechanical of Photo-Fenton system h as been shown big loss by volatilization of these compounds. The Fenton syste m has been shown capable of degradate benzene and toluene compounds, with massic percenta ge of remotion near the 99%.
