| 摘 要： | 以钠基蒙脱石（Na-MMT）为原料,用十六烷基三甲基溴化铵（CTMAB）预先改性,再用羟基铝柱撑液改性,制备不同CTMAB用量的复合改性蒙脱石（CTMAB-Al-MMT）,用于同时吸附水中苯酚和镉离子.复合改性蒙脱石用X射线衍射（XRD）、傅里叶红外光谱（FTIR）表征.结果表明,CTMAB和羟基铝阳离子已有效进入蒙脱石层间,层间距随CTMAB加载量增大而增加,吸附率随CTMAB加载量增大有明显提高.当复合改性蒙脱石用量为0.1g/50mL,吸附时间2h,pH=10时,苯酚吸附率达92.1％,镉离子吸附率达98.8％.

| Abstract: | CTMAB-A1 Montmorillonites complexes taking Na＋-Montmorillonite as rough materials were synthesized, which were premodified with different concentrations of cetyltrimethyl ammonium bromide （CTMAB） and pillared with hydroxy-A1 cations in the end. Simultaneous sorption of aqueous phenol and cadmium ion onto CTMAB-A1-MMT were examined. The results show that CTMAB and hydroxy-A1 cations are effectively into the interlayer and basal spacing is increased with the loading value of CTMAB by X-ray diffraction （XRD） and Fourier transform infrared spectroscopy （FTIR） analysis. The sorption is heighten along with increase of CTMAB. The adsorption rates of phenol and cadmium ion reach 92.1% and 98.8% under condition of CTMAB-A1- MMT dosage 0. 1g/50mL,pH 10 and adsorption time 2h. |
