UV Induced Degradation of Crude Oil in Polluted Water Based on Analysis of Environmental Materials

Abstract

Analysis of environmental materials is very important for the environmental assessment, especially for the crude oil-contaminated water. This paper investigated the degradation of crude oil in the polluted water under the irradiation of UV light, and used the UV absorption, synchronous fluorescence spectra and gas chromatograph to analysis the changes of the environmental materials in the crude oil polluted water during the irradiation. All of the absorbance substances, fluorescent substances and saturated hydrocarbons in the crude oil polluted water decreased with the UV light irradiation. In addition, the dissolved organic matters in the seawater had significant influence on the photodegradation of crude oil.

Dissolution and Photodegradation of Two Crude Oils in Seawater

“…The solution containing water-soluble oil was prepared in the laboratory as our previous work [5]. The reaction solution (100 mL) for GC, UV spectrum and fluorescence analysis was extracted using 20 mL hexane, then concentration.…”
