Cold Plasma Treatment Influence on Aqueous Solution Related to the Electrical Parameters of the Power Supply

The use of electric discharges from laboratory power supplies has increased more and more especially in the field of modern medicine. As the requirements of the plasma treatment increase, so do the complexity of the power supplies. At first the power supply used was the network connected to primary winding of a high voltage transformer, now the new trends are specialized power supplies for specific reactor types in order to both optimize the energy of the power supply and to homogenize the plasma treatment. This paper aims to show the Redox potential of the distilled water after plasma treatment and the time evolution of the electric current and the discharge resistance by using three reactor types connected to a few power supplies both AC and pulsed at different frequencies.
