ABSTRACT
Background and Objective: The base structure of total petroleum hydrocarbons (TPH) is made of
hydrogen and carbon. Widespread use, improper disposal and accidental spills of this compounds lead
to long term remaining of contaminations such as organic solvents and poly aromatic hydrocarbons
(PAHs) in the soil and groundwater resources, resulting in critical environmental issues. In this
study, an oil-contaminated soil was washed using Tween 80 surfactant and the application of photoFenton process (UV/Fe2+/H2O2) for treatment of the produced wastewater was evaluated.
Materials and Methods: Tween 80 is a yellow liquid with high viscosity and soluble in water. In
order to determine of the photo-Fenton process efficiency, we studied effective variables including
Fe concentration, pH, H2O2 concentration, and irradiation time. The UV irradiation source was a
medium-pressure mercury vapor lamp (400 w) vertically immersed in the solution within 2 L volume
glass cylindrical reactor.
Results: The results showed that efficiency of COD removal depends on the initial Fe concentration,
pH, H2O2 concentration and irradiation time.
Under optimum conditions, (Fe: 0.1 mM, H2O2: 0.43 mM, pH: 3 and UV light irradiation time:
2 hours) the removal efficiency of COD was 67.3%. pH plays a crucial role in the photo-Fenton
process such that the removal efficiency increased with decreasing of pH.
Conclusion: According to the results of this study, under acidic condition, this process is an efficient
method for COD removal from the wastewater studied.
