| Abstract: | Corona treatment of Eosin Y-contaminated water by using a dielectric material that covers the ground electrode to avoid spark discharge (causing erosion), reduce charge leakage, and improve the electric field (as stored electrons and charges) was investigated. Elimination of the organic pollutant by gas-phase discharge above the liquid surface in a point-to-plate configuration with multiple needle electrodes was studied. Eosin Y was chosen as model contaminant because of its toxicity and structure that is hard to degrade. Variables such as solution conductivity, dye concentration, pH, air gap, number of needles, and electrode materials were considered. The degree of removal increases with increasing acidity, decreasing concentration, and increasing number of pins. |
