Abstract :
The aim of this paper is to study degradation of a bromophenol blue molecule (C19H10Br4O5S) using direct irradiation of cold atmospheric argon plasma jet. The pH of the bromophenol blue solution has been measured as well as its
absorbance spectra and conductivity before and after the irradiation
of non-thermal plasma jet in various time durations.The
results indicated that the lengths of conjugated systems in the
molecular structure of bromophenol blue decreased, and that
the bromophenol blue solution was decolorized as a result of
the decomposition of bromophenol blue. This result shows that
non-thermal plasma jet irradiation is capable of decomposing,
and can also be used for water purification.
