　　辉光放电电解是一种新型的产生等离子体的电化学方法。在惰性电解质水溶液中进行辉光放电电解，可以产生大量的·OH、·H、e-aq、HO2·等活性粒子，且产物的总生成量超过了根据法拉第定律计算的产量，每通过1 mol电子可生成12 mol·OH。·OH氧化能力非常强，可以无选择地降解各种有机物。文章探讨了电压、初始浓度、pH、催化剂Fe2+等因素对辉光放电降解直接黑EX效果的影响。用紫外可见吸收光谱检测了染料的降解过程。实验表明：利用该方法可以使水中染料大部分降解。直接黑EX优化降解条件为：工作电压610 V，pH 3.12，Fe2+催化作用下降解效率明显提高。

Glow discharge electrolysis (GDE) is a new kind of electrochemical technique for producing plasma. In the glow discharge electrolysis, inert electrolyte solution can produce a lot of active species, such as ·OH, ·H, e-aq, HO2·, and the total yield of product is more than the calculated yield according to Faraday law, for example, each 1 mol electrons can generate 12 mol ·OH. The oxidation ability of ·OH is very strong and it can degrade various organic matter without selection. This work discussed the effect of the voltage, initial concentration, pH and catalyst Fe2+on the degradation of Direct Black EX using glow discharge plasma. The degradation of Direct Black EX was monitored by UV-visible absorption spectra. Experiments showed that this method can degrade most dye in the water. The optimal degradation conditions were as follows:working voltage 610 V;pH 3.12;The catalyst Fe2+can promote the degradation of Direct Black EX.
