摘要
利用电镜、比表面仪和X射线衍射分析方法表征了制备的铝交联蒙脱土。结果表明,OH^-与Al^3+物质的量比、焙烧温度和酸化浓度对交联蒙脱土结构有一定影响,交联剂陈化时间对酸化交联蒙脱土的收率也有影响,最佳条件:n(OH^-):n(Al^3+)=2.2,焙烧温度65℃,酸化浓度5%~20%,交联剂陈化时间1.5天。
Hydroxyl-aluminium cross-linked montmorillonite was prepared and characterized by SEM, BET and XRD techniques. The results showed that OH^-/Al^3+ molar ratio, caMnation temperature and acidification concentration had certain effect on the structure; aging time of the cross-linking agent also had effects on yield of the cross-linked montmorillonite.
