Studied topics
a)
I [mA]
 Development of plasma-liquid system based on dielectric barrier discharge (DBD): water falling film DBD reactor. In this
reactor water/liquid is a part of the discharge electrode configuration and its interaction with atmospheric pressure plasma
generated in different gases (air, N2, O2, He, Ar ) has been studied. (WG2)
Diagnostics of water falling film DBD:
- Electrical measurements and emission spectroscopy: analyses of influence of water film on electrical characteristics of
the discharge and excited species in emission spectra.
- Study of the active chemical species formation in liquid phase (O3, OH, H2O2, NO2-, NO3-, pH, conductivity, oxidation
power).
- Study of the discharge products in the gaseous phase with and without water film (FTIR, absorption spectroscopy, gas
analyzer)
 Applications of water falling film DBD in water treatment, advanced oxidation processes, plasma- catalytic processes and
biomedicine (WG4):
- Degradation of phenols, chlorophenols, reactive textile dyes, pesticides, pharmaceutical compounds
- Removal of arsenic from potable water
- Inactivation of microorganisms in liquids
- Exhaust gas treatment with plasma-assisted scrubbing
 Study of helium DBD plasma jet- a significant plasma source for biomedical applications and surface treatment. (WG2,
WG4)
Diagnostics of He plasma jet:
- Electrical measurements
- Spectroscopic measurement of electric field
- Spatial distribution and time development of some excited species
