“…In principle, the SDBD is generated due to high electric field generated in our case by the triple point effect at the common line between air, liquid electrode surface, and tube wall surface . Detailed description and some characteristics of this type of electric discharge can be found in the work of Galmiz et al Technically, any electrically conductive liquid can be used as the liquid electrode, but from the practical standpoint, low conductivity of solution leads to heating of the liquid electrode. In order to increase the conductivity of water based electrode and prevent the overheating, the 5 wt% solution of oxalic acid (Sigma–Aldrich, p.a.…”
