Sažetak
Degradation of Polyphenols in agro-industrial wastewaters is lately a very important topic because of its complex biodegradation and high phytotoxic and antimicrobial properties that make them dangerous to the environment [1, 2]. The main aim of this study was to investigate the effect of high voltage plasma treatment on polyphenols commonly present in olive mill wastewater. A model solution made of hydroxytyrosol, tyrosol, oleuropein and vanillic acid was prepared at pH values of 7 and 10. Plasma treatment parameters were set at a fixed frequency of 60 Hz, high voltage of 40 kV and 50 kV in combination with air bubbled into the liquid and treatment times 10, 20 and 30 minutes. Physico-chemical parameters (pH value, electrical conductivity, NO2-, NO3- and H2O2) and concentration of polyphenols were determined in all samples. Degradation of polyphenols occurred in all samples, but the most efficient treatment (>90%) occurred at 50kV treatment after 20 minutes at pH 10. The obtained results show potential for further research on the chemistry of degradation intermediates as well as a step forward to the application of high voltage gas plasma discharge on olive mill wastewater decomposition.
