چکیده انگلیسی
We have report a facile, ecofriendly and cost-effective approach to remove toxic heavy metal ions of Pb(II) by magnetically separable reduced graphene oxide/iron oxide (RGO/Fe3O4) nanocomposite synthesized via green method utilizing Murrayakoenigii (Mk) leaves extract as reducing and capping agent. The synthesized RGO/Fe3O4 nanocomposite were characterized using Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), nitrogen adsorption-desorption (BET), vibrating sample magnetometer (VSM) and Raman spectroscopy measurements. RGO/Fe3O4 nanocomposite was used for the removal of Pb(II) from aqueous solution by batch adsorption experiments. The results show that adsorption was followed the pseudo-second-order kinetic model. The adsorption isotherm data fitted well with Freundlich model and Langmuir isotherm, the monolayer adsorption capacity was found to be 48Â mg/g at 301Â K. The results show that the as synthesized RGO/Fe3O4 nanocomposite acts an efficient adsorbent for removal of Pb(II) from aqueous solutions. The overall results of the study indicate that this newly synthesized magnetically separable RGO/Fe3O4 nanocomposite may be potentially utilized for many environmental remediation applications.
