| 要約: | The oil and petrochemical industry is responsable to generate a large amount of waste
and wastewater. Among some efluents, is possible find 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. Oxidative advanced processes, OAP, are
unconventional waste treatment, wich may be apply on 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 degradation. 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. This 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 simulation of condition near of petrochemical
effluents. Different reactors were used for each type of OAP. For the analyticals results of
amount of remotion were used the SPME technique (solid phase microextraction) for
extraction in gaseous phase of these analytes and the gas chromatography/mass espectrometry
The arrangement mechanical of Photo-Fenton system has been shown big loss by
volatilization of these compounds. The Fenton system has been shown capable of degradate
benzene and toluene compounds, with massic percentage of remotion near the 99%. |
