| 摘 要： | 综述近年来国内外蒙脱石的前处理方法及改性蒙脱石的制备方法,并从热分析、X射线衍射、红外分析3个方面对改性蒙脱石的表征手段进行了总结,浓碱稀酸法在蒙脱石的前处理方面效果最好.从表面活性剂、吸附物质、吸附条件的选择和吸附结果等方面,重点探讨了改性蒙脱石对离子型和非离子型有机污染物吸附性能的研究情况,指出单一型改性蒙脱石虽是目前较流行的吸附材料,但复配型及非离子型改性蒙脱石因其具有强吸附剂的分配介质性能和更高的化学稳定性,将成为今后的研究热点.

| Abstract: | The present preparation and modification of montmorillonite were introduced. Organomontmorillonite has been characterized by X -ray powder diffraction, thermal analysis and FFIR. It is pointed out that the concentrated alkali - diluted acid method is the best pre - treatment of montmorillonite. The adsorptive properties of organomontmorillonite to ion and non - ionpollutants from surfactant, adsorption substance,conditions and results are studied. It is pointed out that montmorillonite singly modified with surfactant is currently a popular material, but montmorillonite modified with non - ion and cation/anion surfactant has good chemical stability, so these materials will become the hotspot in the future. |
