摘　　要：对气液两相滑动弧等离子与H2O2联合处理酸性橙Ⅱ溶液进行了研究。结果表明:两者具有明显的协同效应,可减少等离子放电时间,提高了降解效率。质量浓度为300 mg/L的酸性橙Ⅱ溶液,加入体积分数为0.48～0.96 mL/L的H2 O2(30%),循环降解2次的脱色率在92%以上。当加入过氧化氢的体积分数是1.92 mL/L时,循环降解1次脱色率为93.32%。而且降解后的溶液随着放置时间的延长,脱色率进一步降低;且放置8 h时,降解率下降最明显。Combined gas-liquid gliding arc with H2O2 degrading a solution of acid orange Ⅱ was studied.It was found that two techniques had an obvious synergetic effect,decreasing treatment time of discharge and increasing degradation efficiency.Decoloration efficiency was up to 92% after two circling degradations when H2 O2（30%）,whose volume concentration was 0.48～0.96 mL /L;decoloration efficiency was 93.32% after one circling degradations when H2 O2（30%）,whose volume concentration was 1.92 mL /L for 300 mL /L volume concentration acid orange Ⅱ solution.Moreover,decoloration efficiency fell farther with holding time;decoloration efficiency of sampling after once circling degradation fell most distinctly when holding time was 8 h.
