    AbstractCa-montmorillonite was modified with sodium dodecyl sulfate (SDS) and sodium stearate (SSTA) in acidic medium using ultrasound. X-ray diffraction (XRD) analysis, elements analysis (EA), thermal analysis (TG-DTA) and Fourier transform infrared (FT-IR) spectroscopy indicated that the anionic surfactants were intercalated expanding the basal spacing to 3.87nm (SDS/MMT) and 4.80nm (SSTA/MMT), respectively. The dodecanesulfonate and stearic ions entered the interlayer space in the form of ion pairs with Na+. The sulfonate groups of SDS and the carboxyl groups of SSTA formed hydrogen bonds with water molecules in the interlayer space.

    Research Highlights► The intercalation reactions of anionic surfactants, SDS and SSTA, into montmorillonites (MMT) were found and studied. ► The anionic surfactants were intercalated expanding the basal spacing to 3.87nm (SDS/MMT) and 4.80nm (SSTA/MMT), respectively. ► The sulfonate groups of SDS and the carboxyl groups of SSTA formed hydrogen bonds with water molecules in the interlayer space.
