Summary, etc. <p><span>In this study, the adsorption of methylene blue from aqueous solution by modifying sawdust with KMnO</span><span>4 </span><span>has been studied as an effective adsorbent. The surface and characteristics of the composite are studied by Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The result demonstrate, that by increasing </span><em>p</em><span>H, the amount of methylene blue adsorption also increases, and the amount of optimum removal of this dye (96.36%) was obtained at methylene blue dye </span><em>p</em><span>H aqueous solution equal to 6 with initial concentration 100 mg L</span><span>-1</span><span>. The studies have shown that the kinetics of the adsorption process follows the pseudo-second-order model with a correlation coefficient R</span><span>2</span><span>&gt;0.999, and equilibrium data conform the Langmuir isotherm model with R</span><span>2</span><span>&gt;0.9982 and a maximum capacity of single layer adsorption q</span><span>e </span><span>equal to 100 mgg</span><span>-1</span><span>. Thermodynamically, the reaction is endothermic and spontaneous. Consequently, the result has shown, that the modified sawdust can be used as a quick, inexpensive and effective adsorbent in order for removal of methylene blue dye from aqueous solution.</span></p>
