摘要(Abstract)：

对采用溶液吸收结合电化学氧化联合处理甲苯废气进行了实验研究。电化学反应器尺寸为110 mm×110mm×500 mm,反应器内采用5对网状电极叠加分布,阳极材料为网状钌钛电极,共5块,阴极材料为网状不锈钢电极,共5块,两相邻极板间距为45 mm。甲苯模拟废气由化学反应器底部通过气体分布器进入反应器。实验发现吸收液为NaCl时甲苯的去除效果要好于吸收液为Na2SO4的效果。在气体流量为1500 mL·min-1,吸收液为1%NaCl溶液,甲苯废气浓度约为2000 mg·m-3,电流密度0.08 A·cm-2时,甲苯的去除率可以达到80.1%。实验还发现pH值降低有利于提高甲苯的去除率,表明在酸性溶液中更有利于甲苯的氧化反应。通过对反应后吸收液的分析,发现甲苯吸收反应后的产物主要为苯甲酸。
