Paper Title:
Adsorption of Methylene Blue from Aqueous Solution by Anionic Surfactant Modified Montmorillonite
  Abstract

Sodium stearate modified montmorillonite(SSTA-MMT) is prepared by using the anion surfactant sodium stearate, and its structure is characterized by X-ray and FI-IR diffraction. The results show that sodium stearate can be intercalated into the interlayers of montmorillonite and the layer spacing is expanded from 12.74 to 48.05 Å with the loading concentration of sodium stearate increasing from 5 % to 100 % CEC of Na-MMT. The adsorption of methylene blue onto SSTA-MMT experiments show that the adsorption kinetic of methylene blue onto SSTA-MMT can be best described by the pseudo-second-order model and that the adsorption isotherm of methylene blue is in good agreement with the Langmuir equation.
