Investigation of the chemical action of the gliding and "point" arcs between the metallic electrode and aqueous solution

The plasma-solution interaction processes for gliding and "point" arcs betw een the aqueous solution surface and the metal electrode in the gas phase a re studied. The plasma, liquid, and surface zones are taken into considerat ion. The electric field strength is measured, and the gas and electron temp eratures and ion composition are estimated for the plasma zone. The cathode fall, water vaporization rate, and active species current yield due to the radiation chemistry mechanism are determined for the surface zone. The eff iciency of oxidation of iodine ions and organic dyes by different types of discharge in the liquid zone ape investigated. The difference in action of the various discharge types may be connected with various influences of the plasma and surface zone on the oxidation processes.
