| Abstract: | Inserting montmorillonite form Pingliang,Gansu Province was prepared for experiment with different conditions such as reaction temperature,reaction medium and reaction time and an optimum synthesized technique was obtained.The analysis of spectra of FTIR,XRD and TGA showed that the organic agents intercalated into the layers of MMT,the spacing of MMT layers increased form 1.04 nm to 2.11 nm,and the rate of thermo gravimetric analyzer reached 17%.Sedimentation experiment showed that the organic MMT had better dispersibility.This study provided foundation for the further development of natural resources. |
| Keywords: | organic montmorillonite modification of characterization cetylpyridinium chloride |
