نویسندگان
چکیده
Hexavalent chromium is one of the most hazardous contaminants that threaten environment. The present research work involves synthesis Graphene Oxide/Zinc molybdate (GO/ZM) nanocomposite by wet chemical route. structure and morphology synthesized samples were analysed various characterization techniques such as X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), UV-Vis Spectroscopy, High-Resolution Transmission Electron Microscopy (HR-TEM), Brunauer-Emmett-Teller (BET) surface area analysis, Barrett-Joyner-Halenda (BJH) pore size analysis Raman Spectroscopy. efficiency prepared for removing hexavalent from water was investigated performing batch adsorption studies. maximum capacity optimum at using 6 mg adsorbent, under conditions pH 2 with contact time 120 min temperature 283 K. Two isotherm models two kinetic used to study mechanism Cr(VI) ions on GO/ZM nanocomposite. results modelling shows well described Freundlich Isotherm model higher correlation coefficient ( R = .985) follows pseudo second order model.
