【 摘 要 】

The zeolite N.P./PEG/GO composite was synthesized by the hydrothermal assisted sol-gel method to be used as Pb2+ and Cd2+ ions nano-adsorbent from the agricultural water. The FT-IR spectrum confirmed the expected microstructure of synthesized adsorbent. The SEM revealed the formation of zeolite nanoparticles and the layer structure of graphene. The existence of expected elements and crystalline structures were confirmed by EDS and XRD analysis, respectively. The pH, contact time, temperature and adsorption amount was optimized in the removal process of lead (II) and cadmium ions. The results were 6, 20 min, 25 o C and 0.005g for Pb2+ and 4, 20 min, 25 oC and 0.005g for Cd2+ respectively. The adsorption capacity of Lead (II) and cadmium ions were 49.6 and 50.2 mg.g-1 of adsorbent, respectively. Interference ions don’t show any considerable effects on the efficiency of adsorption for both ions. The equilibrium data can well be fixed using both Langmuir and Freundlich equations.
