摘　　要：反应艳蓝KN-R是一种水溶性较好的染料,由于它含有苯环,目前所使用的化学和生物等降解方法效果均不佳。在活性炭的存在下,微波照射能使溶液中的反应艳蓝KN-R迅速降解。对总体积25 mL,浓度为200mg/L的反应艳蓝KN-R溶液微波辐射1.5 min,活性炭的加入量为2.4 g/L,降解率可达83.66%。实验结果表明,微波辐射下活性艳蓝KN-R在催化剂表面被氧化而降解。Reactive Brilliant Blue KN-R is an aqueous solution. Due to phenyl rings are contained in its structure, using conventional technologies include chemical and biological to degrade dye are not so effective. The color of Reactive Brilliant Blue KN-R solution was rapidly taken off by microwave irradiation in the presence of the activated carbon. The degradation ratio reaches 83.66% for 25 mL Reactive Brilliant Blue KN-R solution with 200 mg/L initial concentration and 2.4 g/L active car- bon under 1.5 min microwave radiation. The experimental results show that Reactive Brilliant Blue KN-R is degraded by microwave radiation on the surface of catalyst.
