Abstract

Dielectric barrier discharge being low-temperature plasma generated in cases with an dielectric material between the electrodes is a new method developed recently which has been used to degrade organic pollutants in waste water, because is the hydroxyl radical produced as was shown. Pollution of water with aliphatic organic substances leads to irreversible environmental changes. Physicochemical and biological methods of water treatment are being developed for controlling such pollution. Oxidation of aliphatic organic substances in water by dielectric-barrier discharge discharges was studied. The efficiency of the removal of organic substances from the solutions being treated was evaluated. The authors of the paper designed a plasma reactor that allows the dielectric-barrier discharge treatment of a solution near the surface of the liquid in the flow-through mode, so that this method can be used for technological purposes. Results obtained using a dielectric-barrier discharge for 1-butanol removal are reported in this investigation. The intermediate products and final byproducts were studied. The main intermediate products produced by the dielectric-barrier discharge during the treatment process were 1-butanale and butane acid. These intermediate products disappeared when the treatment time was increased. The concentration of hydrogen peroxide in the aqueous solution at dielectric-barrier discharge contact with the liquid surface was determined. The possibility of hydrogen peroxide formation in water by barrier discharge treatment has been shown, and the change in the redox potential of the system has been analyzed.
