Water pollution is a serious environmental problem. Methylene blue is among the dyes that may exist in waste water. Adsorption is an effective process to remove dyes from contaminated water. Hybrid membranes based on clay-polymer; namely kaolin and polystyrene were prepared to absorb the present methylene blue in aqueous solution. These membranes were fired at 1000 °C to degrade polystyrene leaving cavities in the clay matrix with an expanded surface area and porous structure. The membranes were characterized via X-ray diffraction and In
