Sažetak
Hybrid gas/liquid electrical discharge reactors have been used to degrade an organic dye in the presence and absence of zeolites. Simultaneous gas and liquid phase electrical discharges in the hybrid parallel and hybrid series reactors lead to the formation of hydrogen peroxide and hydroxyl radicals in the liquid phase and ozone in the gas phase. These reactors differ in their electrode configuration, and in previous work it was shown that the ozone levels in the parallel reactor are ten times higher than in the series reactor, while both reactors produce the same levels of hydrogen peroxide as the case with all electrodes submerged in the liquid phase. Solutions of organic dye, C.I. Reactive Blue 137, were decolorized in all cases, however, the series reactor showed the highest removal rate in the absence of zeolites. In the presence of all zeolites (HY, NaY, and NH4ZSM5) the highest dye removal occurred in the parallel reactor. This result indicates that ozone may interact in the presence of corona and zeolite to enhance dye removal.
