AB natural Moroccan illite–smectite was used as an adsorbent for the removal of methylene blue (MB) from aqueous solutions.The clay was characterized by FTIR spectroscopy, TGA, SEM–EDS, X-ray fluorescence, XRD and N2physisorption. Theinfluence of pH, temperature and time on the MB adsorption by the clay was investigated. The maximum equilibriumadsorption capacity was 100 mg g−1 at 45 °C. The kinetic behavior and the isotherms better-fitted with the pseudosecond-order and Langmuir models, respectively. Clay honeycomb monoliths (50 cells cm−2) were obtained by meansof extrusion from the starting material without any additive except water. The structured filters exhibited better performanceunder dynamic conditions than the powdered clay, adding value to the application of this low-cost adsorbent.
