【摘要】 以甲基橙溶液为研究对象,经高压脉冲放电等离子体技术处理,根据处理前后脱色率的变化,考察了放电参数、溶液初始条件、添加剂的投加以及通入气体时对脱色率的影响。结果表明:甲基橙溶液的脱色率随峰值电压的增大而提高,随溶液电导率、初始浓度的增大而降低,随H202的加入,脱色效果显著提高。当电源电压24kv,通气处理30min,甲基橙的脱色率可达95%以上。更多还原

【Abstract】 Methyl orange solution, as the research object, was treated by the technology of high-voltage arc discharge. According to the change of decolorization, the effects of discharge constant, the initial conditions of the solution and addition of catalysts on the decolloration were studied. The results show that the decoloration rate of methyl orange solution was increased with increasing peak voltage, reduced with increasing Conductivity of the solution and Initial concentration,adding H2O2, a great increase in decolorization rate. When the voltage rised to 24 kv, aerated 30 min, the decolorization aboved 95%.更多还原
