This research study aims to decompose bromocresol green (C21H14Br4O5S) using direct irradiation of non-thermal atmospheric pressure plasma jet. The absorbance spectra of the bromocresol green solution have been measured as well as its electrical conductivity and also its pH before and after different time durations of irradiation. The results showed that the lengths of conjugated systems in the molecular structure of bromocresol green decreased, and the bromocresol green solution was decolorized as a result of the decomposition of bromocresol green. This result indicates that cold atmospheric pressure plasma jet irradiation is capable of decomposing and can also be used for water purification.
