Reactor of needle-plate electrode geometry was used. Erosion of tungsten electrodes by the discharge was evaluated. The yields of H2O2 production and decomposition of DMSO by the discharge obtained using tungsten electrodes were compared with that determined for titanium electrodes. The electrode erosion increased significantly with the increasing solution conductivity. Large fraction of the tungsten material released from the tungsten electrode by erosion in the discharge was determined in the solution in dissolved form as tungstate ions. Tungstate ions were shown to play dominant role in the decomposition of H2O2 produced by the discharge with tungsten electrode. Higher degradation of DMSO determined for tungsten was attributed to the tungstate-catalyzed oxidation of DMSO by H2O2 Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2012
