Abstract
Soil vapor extraction (SVE) has been widely used for removal of volatile organic compounds (VOCs) from vadose zone as a safe, economical and efficient technology. Column-venting experiment was used to investigate removal of benzene in the soil by the SVE process. The effects of the soil texture (loamy sand, silt loam and clay) and water content on remediation efficiency were studied. The results showed that the removal efficiency of benzene from the loamy sand soil (98.5%) was higher than that for the silt loan and clay soils (68.3% and 43.4%). In addition, the tail effects were observed in the loamy sand with 20% and 10% water content and the remediation efficiency was lower at higher water content.
