摘　　要：文章以刚果红作为处理对象,探讨了初始浓度、活性炭加入量、pH、微波功率和微波照射时间对处理效果的影响。研究结果表明,含氮染料在水溶液中能在粉末活性炭协助下被微波快速降解:投加2.0 g/L的活性炭,对25 mL的50 mg/L微波照射1.5 min,能达到76.33%的去除率;在同样的条件下,降解率随着活性炭投加量和微波照射时间的增加而上升,最高可达91.78%。Congo red was the object of treatment in this paper.The effect of initial concentration,active carbon powder dosage,pH,microwave power and irritation time has been discussed.The research results showed that Azo dyestuff-congo red in aqueous solution can be degraded rapidly under microwave irradiation in the presence of activated carbon powder： The degradation ratio could reach 76.33 % for 25 mL total volume with 50 mg/L congo red and 2.0 g/L activated carbon powder under 1.5 min microwave irradiation.Under the same condition,the degradation ratio increased by increasing addition amount of activated carbon powder and irradiation time,and the degradation ratio was up to 91.78 %.
