摘    要:以溴化十六烷基三甲铵为改性剂制备有机膨润土,研究了有机膨润土吸附垃圾渗滤液中典型有机污染物苯酚的性能、条件及改性条件对吸附效果的影响。结果表明,有机膨润土对苯酚有很好的吸附效果,实验条件下对苯酚的去除率可达90%以上,pH值是影响有机膨润土吸附能力的主要因素,绘制了不同初始浓度的苯酚溶液在平衡浓度达国家工业废水的第二类污染物三级排放标准时,改性膨润土的用量曲线及吸附等温线,并得到投样量方程:y=0.1959x-0.2458,R^2=0.9751。

关 键 词:有机膨润土  垃圾渗滤液  吸附  苯酚  废水处理

Abstract:Organobentonites were synthsized by placing cetyltrimethylammonium bromide(CTMAB)surfactants on bentonite.The properties,optimal conditions and influencing faetors for organoben-tonites to adsorb typical organic contaminant phenol from refuse percolate were investigated in detail.Removal percentage of phenol under the experimental conditions was over 90%. The pH value wasone of the main influencing factors.The mass curves of organobentonites when the equilibrium con-centrations of phenol meted the discharge criterion of national industrial wastewater for the secondcategory contaminants and isothermal sorption curves of phenol were obtained.The mass equation isy=0.1959x-0.2458, R2=0.9751.
Keywords:organobentonites  refuse percolate  sorption  phenol
