Degradation of Eosin Y in Water by Corona Treatment with a Dielectric Barrier Discharge Plasma

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… Show more

“…The K values after 60 min are 0.0227, 0.01155, 0.0114, 0.0115, 0.0106, and 1.85 × 10 −3 cm min −1 at pH 3, 4, 5, 7, 9, and 11, respectively. The decrease in the rate of SA elimination with increasing solution pH may be attributed to the decline in OH • oxidation potential, which is 2.7 V at pH 3 but 2.34 V at pH 9 40, 41.…”
