Destruction of Toluene by the Combination of High Frequency Discharge Electrodeless Lamp and Manganese Oxide-Impregnated Granular Activated Carbon Catalyst

Figure 4

Removal efficiency of toluene as a function of (a) MnO₂ loading and (b) height of GAC during the O₃/MnO₂-impregnated GAC process. Experimental conditions: (a) [O₃]₀ = 40 ppm; [toluene]₀ = 9 ppm; the height of GAC = 1.6 cm; (b) [O₃]₀ = 40 ppm; [toluene]₀ = 20 ppm; the loading of MnO₂ = 5%.
