摘要：In this study, the effectiveness of local agricultural waste in removing methylene blue dye from aqueous solution (date stones) was investigated. Both batch kinetics and isotherm experiments were conducted in order to determine the sorption behavior of the examined dye. The effects of initial dye concentration, initial pH, adsorbent particle size, and adsorbent dose were studied. The results indicate that the adsorption process follows pseudo second order kinetic models. The particle sizes of the adsorbent and pH had a significant effect on the adsorption process. In addition, a clear correlation was found between augmentation of the initial dye concentration and a subsequent increase of adsorption capacity. The results obtained are consistent with the Freundlich model.
