Influence of Surface Gliding Discharges on Organic Pollutants from Aqueous Solutions

The present paper aims to assess the organic pollutants from aqueous solutions. To achieve this goal, the polluted solutions were treated with non-thermal plasma discharges. To obtain non-thermal plasma an electrical discharge gliding on the surface of the solution, was used. The surface gliding discharges reactors produce an electrical discharge in the gas phase over thin film of aqueous solution. The thin film is produced due to many small droplets of the treated solution atomized in air and argon, as carrier gases. In this manner, can be achieved an enhanced contact between treated solution and the column of discharge. To assess the pollutant removal possibility of non-thermal plasma, the decolorization of an organic water-soluble pigment (e.g. Direct Green 26) was investigated.
