Abstract



In this study, the rice husk (RH) and rice husk ash (RHA) were used as a low cost adsorbent to remove methylene blue (MB) from aqueous solution by batch sorption technique. Effects of initial dye concentration, solution pH, and adsorbent dose on sorption were studied. It was shown that the percent removal also increased when the adsorption capacity (qe) were increased. In the batch system, the adsorption capacity was increased when the parameters were increased until it achieved the equilibrium. The Langmuir and Freundlich’s models were applied to the data related to adsorption isotherm. The optimal parameters for this experiment were 7.5ppm for initial concentration, 0.6g adsorbent dosage and pH 5.8. In the batch system, the adsorption capacity was increased when the parameters were increased until it achieved the equilibrium. The RHA could be employed as the more effective low oval of Methylene Blue Dye from aqueous solution.
