摘　　要：为进一步提高对亚甲基蓝(MB)的降解效果,提出了介质阻挡放电等离子体协同吸附方法,并利用XRD、FTIR方法对吸附剂进行表征分析。研究结果表明,处理120 min后,协同体系对MB的降解率为96.36%。当MB的初始质量浓度为50 mg/L、HNTs的投加量为70 mg/L、放电功率为150 W、pH为6.7、通气量为200 m L/min时,MB的去除效果较好。In order to further improve the effect of methylene blue（MB）degradation,the method by combining dielectric barrier discharge plasma with adsorption synergistically has been put forward,and the adsorbent characterized by XRD and FT-IR methods. The research results show that the degrading rate of MB is 96.36% after a 120-minute treatment by the combined system. When the initial mass concentration of methylene blue is 50 mg/L,HNTs dosage 70 mg/L,discharge power 150 W,pH 6.7 and air flow 200 mL/min,the removal of MB is optimal.
