    Hydrogen peroxide production in capillary underwater discharges

  • Original language description

    Hydrogen peroxide production by an AC driven capillary underwater discharge was investigated quantitatively. Concentration of formed hydrogen peroxide was measured by a colorimetric method using a specific reaction between H2O2 and a titanium reagent. Itcomes out that the amount of H2O2 increases linearly during the first hour of the discharge duration and is slightly higher at the high voltage side of the capillary. The initial rate of H2O2 formation by the capillary discharge was therefore determinedfor initial electrical conductivity of aqueous solution in the range of 100 - 500 S cm-1. The initial rate of H2O2 formation increases with applied power at fixed initial conductivity of aqueous solution. Experiments performed at fixed applied power indicate that the initial conductivity appears to have only negligible effect on the initial rate of H2O2 formation.

    Produkce peroxidu vodíku v kapilárním výboji ve vodě

  • Czech description

    Byla studována kvantitativně produkce peroxidu vodíku v kapilárním výboji ve vodě. Koncentrace produkovaného peroxidu vodíku byla měřena colorometrickou metodou. Byl pozorován lineární nárust H2O2 v první hodině produkce. Byla určena počáteční rychlost formace H2O2 pro rozsah vodivostí 100 - 500 S cm-1. Počáteční rychlost formace H2O2 roste s výkonem při konstantní vodivosti. Pro konstantní výkon naopak , vodivost roztoku počáteční rychlost formace H2O2 příliš neovlivňuje.
