摘 要：Anionic surfactant sodium dodecyl sulfate （SDS）, cationic surfactant cetyl trimethyl ammonium bromide （CTAB） and acrylic acid （AA） were introduced as molecular models to study the interaction between montmorillonite and organic molecules with different charge or chain length. The compounds were characterized by X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FT-IR） and 13C nuclear magnetic resonance （13C NMR）. The results show organic anion could interact strongly with montmorillonite, even the molecules could intercalate into the layers of MMT.
