Original Abstract

Underwater electrical discharges have many potential applications but the study of their creation and physical and chemical properties are challenging. Here a small, multielectrode system is used to explore some of the physical and chemical aspects of plasmas created in NaCl, KCl, BaCl2 and Na2CO3 aqueous solutions. Optical spectroscopy is being used to examine the physical properties of the plasmas while the chemistry induced in the solutions by the plasma is probed by measuring hydrogen peroxide generation and pH. While H2O2 is generated in the first three solutions it is not generated in Na2CO3 aqueous solutions, even though emission spectra shows evidence of OH production in the plasmas created in that solution.
