2.4. Visible emission spectrum and determination of ozone levels
The visible emission spectrum of the plasma discharge was
obtained using a spectrometer (MAYA2000 Pro, Ocean Optics, Inc.,
FL, USA) equipped with the relevant optical setup. The levels of
ozone produced during DBD-plasma generation were measured
using a UV ozone photometer (UVeH; Aeroqual Ltd., Auckland,
New Zealand).
