Abstract

Calcium montmorillonite from Liao-ning was modified by using Cety1 trimethy1 ammonium bromide after it was treated by sodium carbonate.The organic montmorillonite mineral compound materials were prepared.The organic montmorillonite and the original montmorillonite were analysed contrastively by using methods of TEM,XRD and FTIR in this paper.The results showed that the crystal level spacing of organic montmorillonite increased obviously from original 1.556 nm to 2.045 nm,which proved that organic modified effect was very good.
