Abstarct: In this study, the raw graphite as nano-adsorbents has been used for treating dyes and heavy mextals. The analysis of SEM, XRD, CHNS and FT-IR was used to identify the chemical and physical properties of adsorbents. At the beginning, graphite nanoparticles were used as an adsorbent to remove the dyes crystal violet and methylene blue and binary system from aqueous solutions. In order to investigate the adsorption process, influential parameters including pH, adsorbent dosage, concentration and temperature were evaluated. According to the results and the optimal value obtained for each parameter, color contaminants removal rate was over 90 percent. Then, the absorption process were studied in terms of isotherm, kinetics and thermodynamics. According to the isotherm models, it was found that the absorption process of crystal violet followed from Tempkin model and methylene blue followed from Freundlich isotherm model. Also, kinetic analysis showed that both the absorption process followed from the pseudo-second order kinetic model. The thermodynamic process of crystal violet absorption was spontaneous and exothermic, while absorption process of methylene blue was endothermic and Non-spontaneous. In addition, the graphite nano-adsorbents were employed to remove mextal contaminants including lead, cobalt and binary system of these two mextals. In this case, the pH, adsorbent dosage, concentration and temperature were studied to evaluate the absorption process. The maximum removal for mextal contaminants was obtained to be more than 90 percent using graphite nano-adsorbents. The absorption process of both mextals followed the Langmuir model. Hence, adsorption process in binary system baxsed on Langmuir model was investigated. It was distinguished that similarly the adsorption process in the binary system was also described well by the Langmuir isotherm. The sorption kinetics study showed that both lead and cobalt ion adsorption process was according to pseudo-second-order kinetic model. Lead ion adsorption process thermodynamically was endothermic and exothermic and cobalt ion adsorption process was spontaneous and Non-spontaneous.
