摘要
以十六烷基三甲基溴化铵(HTMAB)、自制的低分子质量聚胺及四甲基铵对膨润土进行有机改性,通过红外光谱、X射线检测分析证实,HTMAB可有效地与膨润土进行复合,并以一定角度倾斜于层间。不同有机胺改性膨润土对松香酸吸附性能的研究结果表明,改性膨润土中需复合一定强度的有机相,才能更有效地吸附有机污染物松香酸。
Montmorillonite was modified with hexadecyl trimethyl ammonium bromide（ HTMAB） and the organo-montmorillonite was characterized by infrared spectroscopy（IR） and X-my diffraction（XRD）. It was found that HTMAB was intercalated into motmorillonite, arrayed at an angle between the layers, For comparison, the montmorillonite complexes modified with low relative molecular weight poly-ammonium and tetramethylammonium were prepared, and their adsorption ability was evaluated. It was found that the organic phase formed by quaternary ammonium enhances the compatibility between montmorillonite and rosin acid, therefore the adsorption capacity of the modified clay was improved.
