DC Diaphragm Discharge in Water Solutions of Selected Organic Acids

Popis výsledku v původním jazyce

This work concentrates on plasma discharge in water solution of two simple organic acids. Diaphragm discharge configuration is used, when the reactor is divided into two parts by a dielectric barrier with a small orifice. That enables study of processesunder both polarities at the same time. The efficiency of the discharge is quantified by the hydrogen peroxide production, determined using UV-VIS spectrometry of H2O2 complex with titanium reagent. Optical emission spectra (OES) were obtained during thedischarge to evaluate the differences for two concentrations of the acids and a selected reference solution of NaCl. Formic and acetic acids were chosen. Results show higher hydrogen peroxide production when acids are used in concentration of 1 mmol l-1compared to the reference solution ? the values obtained reached 1.57 and 1.29 g/kWh for the formic and acetic acid, respectively, while it was 1.16 g/kWh for the reference solution. On the other hand, addition of acid in concentration of
