dc.description.abstractAdsorption is an effective method for the removing of heavy metals in the industrial waste water. Improvement of the efficiencies of the adsorbents can be possible by reduction of the particle size into nano scale. Therefore, in this study, zeolite nano-particles were synthesized by classical and microwave heating methods and then determined their adsorption capacities for the lead and nickel cations during batch adsorption processes carried out at 25C with different adsorbent loading and initial metal concentrations. Results obtained from X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis revealed that the synthesized zeolite nanoparticles was pure NaX with ultrafine and uniform particle sizes around 170 nm and Si/Al ratio of 1.24. Batch adsorption studies at 25C revealed that, NaX nanoparticles have high affinities against lead, nickel and methylene blue dye. As the initial metal and dye concentrations were increased, sorption capacity of the NaX was increased and reached the maximum value of 0.99, 1.33, 2.11, 1.89 and 0.15 mmol /g for the lead, nickel, copper, silver and methylene blue cations respectively. Sips model equation successfully described the equilibrium adsorption data of all adsorbates. Adsorption experiments of NaX for heavy metals from a real wastewater indicates that although the solution contains calcium and potassium ions in huge concentrations, the adsorbent is capable to adsorb lead and nickel even if they are low in concentrations. © 2019 Gazi Universitesi Muhendislik-Mimarlik.
