Diesel oil volatile loss and the moisture content of soil during drying

Volatilizauon of diesel oil in soil columns was conducted at the ambient temperature of 20 °C by spilling oil on soil surface. The weight loss of oil was determined by pre and post weight of the soil columns and desiccant measured on an electronic balance. The aim of this paper was to investigate the effect of moisture content on the volatilizauon of diesel oil in soil. The results show that the diesel oil and water in soil both volatilize at a linear rate with respect to time. The largest volatilizauon mass of diesel oil and water reach when the moisture contents are 12% and 22% respectively. Appropriate water content can help to pull the oil contaminants to the surface of the soil. ©2010 IEEE.
