Description
  • Hydrogen peroxide as the most abundant chemical species directly produced by the discharge in water is often utilized in Fenton's reaction to increase the plasmachemical efficiency of the removal of organic compounds by addition of ferrous salts into treated water. There is also evidence about contribution of H2O2 in bacterial inactivation by electrical discharge in water. In the present study, the role of solution conductivity in the hydrogen peroxide production by the pulsed corona discharge in water generated using point to plane geometry of electrodes is investigated. The free radical scavenging property of DMSO and KBr is used to determine the initial rate of formation of H2O2 by the pulsed corona discharge. The influence of UV radiation of the discharge and the effect of H2 on the production of hydrogen peroxide will be discussed.

  • Peroxid vodíku je nejvýznamnějším chemickým produktem elektrického výboje ve vodě. V přítomnosti železnatých solí výrazně zvyšuje účinnost plazmochemického rozkladu organických látek ve vodě v tzv. Fentonově reakci. Přispívá také k antibakteriálnímu účinku elektrického výboje ve vodě. Tato práce se zabývá vlivem vodivosti roztoku na produkci H2O2 impulsním korónovým výbojem ve vodě generovaným v elektrodové konfiguraci hrot-rovina. Produkce H2O2 je zkoumána v závislosti na přítomnosti a koncentraci zhášečů OH radikálů v roztoku (DMSO a KBr). Dále je diskutován vliv UV záření a H2 generovaných výbojem na produkci peroxidu vodíku. (cs)
