摘    要:以溴化十六烷基三甲铵为改性剂制备有机膨润土,利用正交实验研究了有机膨润土吸附垃圾渗滤液中极性有机污染物苯胺的性能、条件及改性条件对吸附效果的影响。结果表明,有机改性膨润土对苯胺有很好的吸附效果,实验条件下对苯胺的去除率可达90%以上,绘制了有机膨润土吸附苯胺的吸附等温线,通过与吸附苯酚效果的比较,总结了有机膨润土吸附极性有机污染物的一般规律。

关 键 词:有机膨润土  吸附  极性有机物  苯胺  垃圾渗滤液  废水处理

Abstract:Organobentonites were synthesized by placing cetyltrimethylammonium bromide(CTMAB)surfactants on bentonite.The properties,optimal conditions and influencing factors for organo-bentonites to adsorb polar organic contaminant aniline from refuse percolate were investigated in de-tail using orthognal experiments.Removal percentage of aniline under the experimental conditionswas over 90%,the equilibrium concentraion of aniline meted the discharge criterion of national in-dustrial wastewater for the second category contaminants.The pH value was one of the main influ-encing factors to adsorb polar organic contaminants.The isothermal sorption curves of aniline wereobtained and the laws of sorption to polar organic contaminants were summarizd.
Keywords:organobentonites  sorption  polar organic  contaminants  aniline
