Abstract
It is necessary to remove toluene due to its doing harm to people's health in its wide use. Dielectric barrier discharge (DBD) produces non-thermal plasma to remove toluene using high frequency alternating current (AC). Based on the elements of circuit and DBD, the effects of reactor structure, voltage, frequency and power on removal efficiency of toluene were tested. The byproducts and decomposition mechanism of toluene were analyzed. The experimental results show the 99-ceramic reactor of DBD is helpful for toluene removal than the quartz glass reactor. The frequency and power are nonlinearly related with the removal efficiency. If harmonic frequency occurs, the highest power belongs to reactor, and removal efficiency reaches its maximum value. The byproducts include aldehyde, alcohols, amide, and benzene detected by GC-MS.
