Abstract

This research presents a thorough spectroscopic investigation of atmospheric- plasma generated by a plasma jet. The study examines the plasma behavior under varying flow rates of argon gas. A primary objective is to identify the optimal flow rate that facilitates the application of the generated plasma in sterilization and bacterial eradication operations. The findings establish a correlation between argon flow and critical plasma parameters, specifically noting variations in electron temperature (T_e) & electron number density (n_e). Crucially, the study demonstrates that lower argon flow rates are more effective in generating active species such as hydroxyl and NO reactive species. The results of this investigation hold significant promise for advancing our comprehension of plasma jet technology's utility in sterilization or medical treatment processes, emphasizing the importance of gas flow optimization for these applications.
