Synthesis and characterization of MgO/PEG/GO Nanocomposite and its application for removal of Copper (II) from aquatic media
Abstract
In this study, MgO/PEG/GO nanocomposite was synthesized by a sol-gel and solvothermal methods. with three chemical compounds that had adsorption property. Microstructure of synthesis nanocomposite was investigated by XRD, SEM and FT-IR. The XRD pattern confirms crystalline structure of MgO and GO. The SEM images validate formation of MgO particles on GO layers in Nano size. The analysis EDX is shown in the presence of magnesium and FT-IR result shows expected structure. The MgO/PEG/GO nanocomposite was used for removing copper (II) ion from water and the effective factors on removal were optimized. The results showed that the maximum of removal in pH, amount of adsorbent and contact time are equal to 7, 0.01 g and 20 minutes respectively. Investigating the effect of interfering ions had no considerable effect on removal efficiency.
