| 摘 要： | 以阳离子表面活性剂十六烷基三甲基溴化铵(HDTMAB)为柱撑剂对怀俄明钠基蒙脱石进行改性,获得了不同质量浓度的有机改性黏土(0.5～2 5CEC).通过对改性蒙脱石吸附苯酚的XRD、TEM和热重分析的实验研究,发现改性后蒙脱石的层间距明显增大.实验结果表明随着改性活性剂质量浓度的加大,HDTMAB有机离子逐渐由单层变为双层直至三层.有机蒙脱石去除水溶液中苯酚的能力也相应地得到了很大的提高,吸附效果明显增强.

| Abstract: | Organoclays were synthesized by the ion exchange of cationic surfactant-HDTMAB for sodium ions in an aqueous solution with Wyoming Na-montmorillonite.The characterization of organoclays with and without adsorbed phenol was determined by X-ray diffraction,TEM and thermal analysis.The results of experiments showed that organic ions of HDTMAB gradually changes in the order of monolayer,lateral bilayer and paraffin-bialayer with the increases of interlayer spaces of organoclays.The adsorption efficiency for phe... |
