Dissolution and Photodegradation of Two Crude Oils in Seawater

Abstract:

The fate of oil spilled on seawater is an important issue for marine environment. This paper studied the dissolution of two crude oils and the photodegradation of their water-soluble fraction (WSF). The relationship between the solubility and the component of the crude oils was studied by gas chromatograph, UV absorption and synchronous fluorescence spectrum, and the result indicated that the aromatic hydrocarbon was liable to dissolve in water and the dissolved organic matter (DOM) in seawater enhanced the dissolution of crude oils. Moreover, the photodegradation of WSF accorded with the pseudo-first order reaction, and the reaction rate constants for WSF 1 and 2 were 0.088 and 0.121 h^-1, respectively. This investigation is helpful for better understanding the transformation of crude oil spilled on the sea.
