The equilibrium sorption evaluation of RB5 conformed and fitted well to Langmuir adsorption isothermmodels and the maximum sorption capacity was 0.606 mg/g. The kinetic adsorption models followedpseudo-second order model and the dye intra-particle diffusion may suggesting a chemical reactionmechanism. Further, it was obvious from the investigation that this composite could be applied as apromising low cost adsorbent for anionic dye removal from aqueous solutions.
