It is known that industrial wastewaters containing textile dyes comprise organics that are difficult to bio-degrade and when they are discharged to receiving bodies, they cause serious impacts on environment. Therefore, this kind of wastewaters require advanced treatment besides conventional ones. Adsorption is accepted one of the favorable processes, which can be applied integrative to conventional systems during the treatment of this kind of wastewater. In addition to the effectiveness of the materials to be utilized in the adsorption process, their cost and availability are also very important factors. In this study, the effi-ciency of environmentally friendly, cost-effective powdered graphite in the removal of diazo type textile dye (Direct Red 243) color from aqueous solution by adsorption was investigated. For this purpose, Response Surface Method was applied via Box-Behnken Design and the most effective parameters were investigated in dye adsorption with graphite. Adsorption study was carried out in batch mode and pH (2-10), adsorbent amount (0.1-1.5 g) and time (15-65 min) were designated as experimental parameters. It has been observed that the most effective parameter in color removal of dye was pH and at low values of this parameters the higher efficiencies were obtained. Additionally, it was observed that the increase in the amount of adsorbent increased the efficiency, and time had no significant effect besides two parameters. Almost complete decolorization (98%) was acquired at pH 2 with 1.5 g adsorbent for 40 min of study. As a result of the study, even it is not expanded further applications, the graphite can be effective for anionic dye color removal under acidic conditions by its pristine form.
