| 摘 要： | 以辽宁某地钙基蒙脱石为原料，经碳酸钠钠化改型后，用十六烷基三甲基溴化铵作插层剂对其进行有机插层处理，考察插层剂的最佳用量。采用XRD、FTIR和DTA／TG等测试技术对所研制的蒙脱石有机插层复合物进行表征，结果表明，插层剂用量为120％mmol／100g CEC时所制备的蒙脱石有机插层复合物的插层效果最好。

| Abstract: | Calcium montmorillonite from Liao-ning was organic-intercalated by using cety1 trimethy1 ammonium bromide after it was treated by sodium carbonate.The optimal amount of intercalating agent was reviewed.Organic-intercalated montmorillonite composites were characterized by the methods of XRD,FTIR and DTA/TG in this paper.The results showed that the organic-intercalated montmorillonite composites was best when the amount of intercalating agent reached 120% mmol/100 g cation exchange capacity(CEC). |
