摘要

利用十八烷基三甲基溴化铵改性钠基膨润土（Na-MMT）制备了有机膨润土（O-MMT）。利用傅里叶红外光谱仪、X射线衍射仪、透射电镜和吸附仪表征了其形貌和结构特征。结果表明有机离子通过离子交换作用进入钠基膨润土层间，d001晶面间距由1.26 nm增加到3.80 nm。利用其作为吸附剂，研究其处理港口含油废水的性能。与Na-MMT对比，O-MMT对油和COD的去除率分别是Na-MMT的2.5倍和5倍。通过研究搅拌时间、吸附剂的用量和循环使用次数对吸附性能的影响，表明室温下，投加2 % 吸附剂，搅拌30 min是处理含油港口废水的最佳条件，该吸附剂可循环使用3次。

Abstract

Organmontmorillonite (O-MMT) was modified by surfactant-octadecyltrimethylammonium bromide with Na-montmorollonite (Na-MMT).The characteristics and structure of the sorbent were investigated by Fourier transform infrared ray spectroscopy (FT-IR)

X-ray diffraction (XRD)

transmission electron microscope (TEM) and BET analysis.The results indicated that organic cations were exchanged into Na-MMTs stacks and the basal spacing (d001) increased from 1.26 nm to 3.80 nm.Then O-MMT was used as sorbent to treat oily wastewater from port.Comparing to Na-MMT

the COD (chemical oxygen demand) and oil removal increased by 5.0 times and 2.5 times

respectively .The effects of agitation time

the amount of O-MMT and recycle times of O-MMT were investigated and the optimum experiment condition at room temperature was established: adding 2.0 % O-MMT and agitating 30 min.The duty-cycle operation of O-MMT was three times.
