摘要: 研究石油中3种常见组分四氢萘、 乙苯和十氢萘在人工光源以及太阳光照射下光化学降解的可行性. 结果表明, 在波长小于290 nm的紫外光照射下, 四氢萘、 乙苯和十氢萘均可以发生直接光解; 而在ZnO, TiO2以及Fenton试 剂存在的条件下, 上述物质可在波长大于290 nm的光的作用下发生间接光解.

Abstract: The photodegradation of the three cyclic hydrocarbons in petroleum, ethyl benzene, tetrohydronaphthalene anddecahydronaphthalene was s tudied. A high pressure mercury lamp and the sunlight were respectively used as the light sources. The results of the experiments showed that the three componen ts all could be photodegraded under the high pressure mercury lamp, but not unde r the sunlight. When there is Fenton reagent (Fe2++ H2) or particles of TiO2 or ZnO in the reaction system, the three cyclic hydrocarbons could all be degraded under either the high pressure mercury lamp or the sunlight. The sequence of the rates of the photodeg radation wastetrohydronaphthalene>decahydronaphthalene>ethyl benzene. The opt ium photodegradation conditions were selected.

Key words: hydrocarbons in petroleum, photodegradation, water
