大气压介质阻挡放电降解水中苯胺
DOI: 10.3969/j.issn.1671-7627.2013.06.003, PP. 11-16
Keywords: 介质阻挡放电(dbd),低温等离子体,苯胺,降解
Abstract:
采用大气压介质阻挡放电对含苯胺的废水进行了处理,研究各种因素对苯胺废水处理效果的影响,对处理过程中溶液的总有机碳(toc)、ph和电导率的变化进行了测定,探讨放电特性和机制。结果表明:苯胺降解率随反应时间的延长而增加;初始浓度升高,苯胺去除率降低,去除量增加;电导率增加、溶液中添加na2so4和nano3时均会降低苯胺去除率;投加h2o2对dbd起协同作用,电极距液面4mm,放电功率235w,反应10min时去除率最高由35.76%增加至89.86%。
