| Abstract |
The contamination of subsurface soil and groundwater by volatile organic compounds (VOCs) is a pervasive problem in the United States. However, the powerful photochemical reactions in the vapor phase have not been used for the treatment of the VOC air emission. Recently photolysis of some VOCs from soil vapor extraction (SVE) at ambient temperature was studied. The results showed that the reactioins were slow and failed to mineralize the VOCs. The authors have recently developed a photothermal process that overcomes the problems encountered previously. It has been demonstrated that the light absorbed by many VOCs increases the intensity and broadens the absorption region with a rise in temperature. It has also been shown elevated temperatures significantly increase the rate of photothermal reactions making this process a viable option for the destruction of the vapor of VOCs. |
