“…The key parameter of the plasma jet when ignited using mixture of argon and oxygen, is the generation of powerful oxygen based reactive species; these species are delivered to the suspension and result in the creation of secondary reactive species with antimicrobial potential [6,14,15]. Using optical emission spectroscopy we could identify the main species generated by the plasma jet at the first place.…”

“…Julie Chauvin et al employed a plasma jet to treat liquids and found that the reactive species formed in it, along with a considerable shift in the pH of the solution, were the factors accounting for the liquid's antibacterial potential that is gained subsequent to the plasma treatment [3]. Several other studies can be found in literature have used plasma jets for liquid treatment for bacterial inactivation, including the studies of Bhagirath Ghimire et al [4] and McKayla J. Nicol and his co-workers [5] and many more [6][7][8]. A particular plasma jet setup has been developed and well described in previous work [9], this setup offers a relatively easy and safe way to perform treatment of aqueous solutions.…”

Plasma based treatments are found to be effective in water cleansing. For this purpose, we employed a plasma jet that is extracted at the exit of a flexible plastic tube remotely from its main source. This plasma jet is generated using a gas mixture of argon and oxygen for the sake of producing reactive oxygen species in the solution when submerged safely under water to perform a treatment in the suspension volume. The treated samples consist of distillated water that is contaminated with bacterial cells of Pseudomonas aeroginosa, this bacteria can present extreme threat to the human body and may lead to death. Our study reports the effect of both treatment time and the introduced ratio of the gas mixture introduced to ignite the plasma discharge. Results illustrate that full water decontamination can be obtained after about 12 minutes of treatment using 1.5 slpm of argon gas flow in addition to 2.5±0.2% of oxygen.
