Abstract :
Background and Objective: In this study, we compared the efficiency of pure GO (Graphene oxide) and GO modified with EDTA as an absorber for methylene blue and some heavy metals such as copper, lead, and arsenic. Regarding the structural properties of EDTA, we expected that after attaching EDTA to GO, the effect of modified GO in adsorption of pollutants, increased. Based on the characteristics of synthesized nanohybrid, methylene blue (MB) absorbed through interactions with GO levels through π-π interaction, as well as electrostatic interactions with EDTA. Heavy metals adsorbed to modified GO by forming a complex compound.
Material and Methodology: X-ray powder Diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), UltraViolet-Visible Spectroscopy (UV-Vis) were approved.
Findings: 0.03 grams of synthesized modified GO eliminated 30 ml of contaminants at a concentration of 1 g/l in the first 30 minutes.
Discussion and Conclusion: The results show high removal efficiency in the first 30 minutes witch that confirming the effect of modified GO on color removal efficiency.
