| 摘 要： | 分别用溴化十六烷基三甲铵（ＣＴＭＡＢ）和氯化十六烷基吡啶（ＣＰＣ）改性膨润土，研究了制备有机膨润土的适宜条件及其对吸附对对硝基苯酚性能的影响。２５℃时，ＣＴＭＢ－膨润土和ＣＰＣ－膨润土对对硝基苯酚的饱和吸附量分别为４７５ｍｇ／ｇ，远大于原土的饱和吸附量（１２５ｍｇ／ｇ）。ｐＨ〉７时，有机膨润土吸附处理对硝基苯酚的去除率都在８５％以上，比原土的去除率（８．６％）大９倍，通过Ｘ－衍射、红外光谱分析、比

| Abstract: | Two organoBentonites were synthesized by PLacing quaternary ammonium surfactantssuch as cetyltrimethylammonium bromide(CTMAB )and cetylpyridinium chloride(CPC )on bentonite,They were examined for their ability to adsorb p-nitrophenol.The saturationadsorbing capacities of CTMAB-bentonite,CPC-bentonite and original bentonite for p-ni-trophenol are 475 mg/g,400 mg/g and 125 mg/g,respectively.The removal rates fororganobentonites to treat p-nitrophenol in wastewater are more than 85%. The removalrates of p-nitrophenol and COD in wastewater were improved by organobentonites with alu-minum sulfate. The structure of organobentonites and the mechanism for their adsorptionare studied by X-ray diffraction(XRD),infrared spectra and BET area. |
