摘　　要：针对水中酚类有机污染物的去除,十六烷基二甲基苄基氯化铵(HDBAC)和十六烷基三甲基溴化铵(CTMAB)为改性剂在制备了两种有机膨润土(HDBAC-Bent和CTMAB-Bent),并以红外光谱和扫描电子显微镜对有机膨润土的结构进行表征.同时,考察了有机膨润土对单一和复合污染体系中苯酚和2-萘酚的吸附性能,研究发现两种有机膨润土对2-萘酚的吸附能力远远大于对苯酚的吸附,在两种有机物共存时,2-萘酚的吸附受苯酚影响很少,而苯酚的吸附显著受到抑制.Aiming to the removal of phenols from water, organobentonites （HDBAC-Bent and CTMAB-Bent） were fabrica- ted with HDBAC and CTMAB as modifiers, and their structure were characterized with FTIR and SEM. The adsorption ca- pacities of organobentonites towards phenols from single-solute and bi-solute system were studied. It was found that the ad- sorption ability of the two organobentonites towards 2-naphthol was remarkably higher than that towards phenol. In the bi- solute system, the adsorption of 2-naphthol was hardly effected by coexisted phenol, while the existing of 2-naphthol dra- matically reduce the adsorption of phenol. Comparing to CTMAB-Bent, the adsorption ability of HDBAC-Bent towards 2- naphthol was much higher.
