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.

介质阻挡放电等离子体电晕处理降解水中的曙红Y
通过使用覆盖接地电极的电介质材料对电晕剂处理曙红Y污染的水进行了研究，该材料可避免火花放电（引起腐蚀），减少电荷泄漏并改善电场（作为存储的电子和电荷）。研究了在具有多个针状电极的点对板配置中，通过液相上方气相排放来消除有机污染物。曙红Y因其毒性和难以降解的结构而被选作模型污染物。考虑了诸如溶液电导率，染料浓度，pH，气隙，针数和电极材料等变量。去除程度随酸度增加，浓度降低和销钉数量增加而增加。
