| 摘 要： | 利用甲胺消弱α-磷酸锆(α-ZrP)层间作用力, 合成了不同十六烷基三甲基溴化铵(CTMAB)含量插层α-ZrP的复合物CTMAB-ZrP. 通过X射线粉末衍射(XRD), 傅里叶变换红外(FTIR)光谱, 透射电子显微镜(TEM), 扫描电子显微镜(SEM)及氮气等温吸附对CTMAB-ZrP进行了表征, 推测了CTMAB在磷酸锆层间的排列形式. CTMAB-ZrP吸附水中苯酚的实验结果表明, CTMAB-ZrP对苯酚的吸附量不仅与CTMAB的插入量和层内空间位阻有关, 还与溶液的pH值密切相关. 对苯酚、2-氯苯酚、2,4-二氯苯酚、对甲基苯酚及3,5-二甲基苯酚的吸附实验结果表明, CTMAB-ZrP对酚类化合物的吸附量与酚的疏水性成正相关, 而与酚类化合物的酸性无关. Henry型和Freundlich型吸附等温方程都能很好地拟合CTMAB-ZrP对苯酚、2-氯苯酚和2,4-二氯苯酚的吸附过程, 表明吸附主要是酚在插层复合物层间有机相中的分配作用所致.

| Abstract: | Cetyltrimethyl ammonium bromid(CTMAB)-ZrP complexes that contained different amounts of CTMAB that intercalate into a-zirconium phosphate were successfully prepared while methylamine weakened the interlayer forces in a-zirconium phosphate.The CTMAB-ZrP samples were characterized by Fourier transform infrared(FTIR) spectroscopy,X-ray diffraction(XRD),transmission electron microscopy (TEM),scanning electron microscopy(SEM),and N_2 sorption isotherm analysis.We discuss the arrangement of CTMAB in the interlaye... |
