A palygorskite/carbon composite was prepared through hydrothermal treatment of palygorskite and cellulose, and its adsorption behavior for methylene blue ( MB) was investigated. The effect of adsorption conditions on the capacity and kinetics was also investigated. The adsorption kinetics of MB onto the composite is best described by a pseudo_second_order equation. The ad_sorption isotherms conform to the Langmuir isothermal adsorption equation. The adsorption thermodynamic parameters calculated from the isotherms indicate that the adsorption of MB on the composite is endothermic.
