Abstarct: At the present time, industrial wastes containing dyes and heavy mextals are one of the most important environmental pollutants. These industrial wastes which are being discharged to the nature have a number of serious implications for the environment, human being and other live creatures. Among various methods which have been carried out in order to remove these pollutants, adsorption method is the most favorable method because of a wide range of different reasons. Its low cost initial expenditure along with its simple and flexible design makes it a very distinct method. From the other perspective, it offers a very easy operation process. Its non-sensitivity to the pollutants and toxic compounds also introduces adsorption method as a preferred method. In this study, a porous pegmatite nanocomposite both the raw samples and those modified by acid and baxse has been used to remove the methylene blue and malachite green dyes pollutants and the lead(II) ion contaminatuion. The physical, surface and morphology characteristics’ of adsorbents were determined using the XRD, XRF, SEM and FT-IR analysis and the effects of parameters such as pH, the contact time between pollutant and adsorbent, adsorbent dosage, the initial concentration of pollutant and temperature on the amount of adsorption have been investigated. The optimized pH for methylene blue and malachite green dyes and the lead(II) ion pollutant were 10, 9 and 6.5, respectively. Both equilibrium and kinetic adsorption were experimentally considered. The results clearly illustrates that the adsorption process of methylene blue and malachite green pollutants and the lead(II) ion pollutant are in conformity with Redlich-Peterson, Sips and Sips Isotherm models, respectivily. The adsorption capacity of methylene blue and the lead(II) ion pollutants using raw porous pegmatite nanocomposite and modified by NaOH, Citric Acid, Nitric Acid, Citric Acid / Nitric Acid, Citric Acid / Nitric Acid / NaOH Were (18.76, 8.98), (18.428, 27.63), (18.69, 15.63), (27.75, 7.44) and (26.8, 11.76), respectively. The study of kinetic adsorption process demonstrates that kinetic experimental data follow the pseudo-second-order kinetic model. Thermodynamic studies implies that both raw and activated porous pegmatite nanocomposite can be used as a very suitable adsorbent to control and treatment of polluted wastes.
