Abstract In this study, the degradation effect of two typical VOCs (toluene and acetone) in NTP sole, NTP+ LC/Fe²⁺ and NTP+ LC/Fe²⁺+PCA systems were comparatively investigated. The results showed that the removal rate of both toluene and acetone increased with discharge voltage, and the degradation efficiency of toluene was higher than that of acetone at the same voltage. The amount of O₃ produced during the degradation of toluene or acetone was similar. At a discharge voltage of 22kV, toluene removal efficiency of NTP+ LC/Fe²⁺+PCA increased by 18.2% while acetone removal efficiency increased by 55.5% compared to NTP sole. O₃ removal rate reached 100% in the NTP+ LC/Fe²⁺+PCA system. EPR and burst experiment results showed that hydroxyl radicals and superoxide radicals played important roles for the removal of VOCs in LC/Fe²⁺+PCA systems. Finally, the degradation pathway of VOCs in the NTP+ LC/Fe²⁺ system was postulated basing on the detected free radicals and intermediate organic products.
