接触辉光放电等离子体处理染料废水

Treatment of dye wastewater with contact glow discharge electrolysis

以酸性黄和弱酸红为例 ,利用接触辉光放电电解对水溶液中的染料降解进行了研究 ,讨论了放电条件对染料降解率和脱色率的影响 ,并对接触辉光放电电解处理染料废水的实验条件进行了优化。结果表明 :在接触辉光放电电解过程中 ,升高温度对降解率和脱色率有消极影响 ;在电解液中加入过渡态金属离子 ,脱色率和降解率都明显提高 ,其中 。

Contact glow discharge electrolysis (CGDE) for two dyes, weak acid brilliant red B (RB) and weak acid flavine G (FG) was investigated under different concentrations, temperatures and medias. The effects of these conditions on degradation rate and decolorization rate were discussed. The optimum conditions were obtained from the experiments.
