Abstract

The chemical properties of the gaseous species generated in a humid airgliding arc discharge are investigated. Aqueous solutions are used as the targetsexposed to the plasma, and this allows to evidence strong acid and oxidizing effectson various solutes by means of spectrometric or potentiometric methods. The influenceof some working parameters such as the input gas flow, the distance from theelectrodes to the target or the electrode gap is examined on the chemical transformand simple experimental laws are derived. A general feature is observed for oxidationand suggests the occurrence of an auto-catalytic step in the relevant kineticmechanism.
