摘要/Abstract

摘要： 采用离子交换法直接用十六烷基三甲基溴化铵处理钙基蒙脱土，成功制备出理想的有机蒙脱土，经红外光谱分析（FTIR）、差热分析（DTA）和X射线晶体衍射(XRD)分析等测试手段表征. 研究了蒙脱土处理方式、离子交换时间和次数对有机蒙脱土结构的影响. 结果表明, 有机蒙脱土的层间距由1.49　nm扩大到2.21　nm.

关键词: 钙基蒙脱土, 离子交换法, 层间距

Abstract: A new type of organomontmorillonite (C₁₆-MMT) is reported. Camontmo rillonite (Ca-MMT) was directly modified with hexadecyl trimethyl ammonium bromide viaionexchange. The effects of dispose measure of montmorillonite and ionexchange conditions including ionexchange time and ionexchange times on the structure of C₁₆-MMT were investigated by X-ray diffraction (XRD). The X-ray patterns reveal that the interlamellar spacing of the clay, corresponding to the (001) plane peak, increases from 1.49　nmof the purifiedCa-MMT to 2.21　nm of C₁₆-MMT.

Key words: Ca-montmorillonite, ion-exchanged method, interlamellar spacing
