埃洛石吸附-介质阻挡放电等离子体处理亚甲基蓝废水

摘要

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.%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 mL/min时,MB的去除效果较好.
