Synthesis and characterization of the hyperbranched polymers based on nanoparticles for removal of pollutant from water
Harmful heavy metals have a significant effect on the toxicity of wastewater due to their non-biodegradability; hence, they will harm living things. Graphene oxide has been studied in recent research to remove these heavy metals. This study was carried out to determine the characterization of graphene oxide-based hyperbranched polymers (GO-MHBP) and their batch experiments on removing heavy metals (Cr3+ and Hg2+). The surface of the graphene oxide particles was modified by 3-(aminopropyl) triethoxysilane, and then hyperbranched polymers were fabricated by incorporating 3,5-diaminobenzoic acid and maleic anhydride. The synthesized polymers were characterized physically and morphologically using FT-IR, FE-SEM, EDX, and TGA techniques. Moreover, they were assessed in terms of adsorption capacity to remove pollutants of Cr3+ and Hg2+. To that end, the effect of pH, adsorbent amount, contact time, and initial concentrations of metal ions was evaluated. Furthermore, the adsorption kinetics and isothermal behavior were investigated for the adsorption efficiency of GO-MHBP nanocomposite. The adsorption process was consistent with the second-order kinetic model and the Langmuir isotherm model. Eventually, the GO-MHBP could serve as promising adsorbents for potential application in the removal of Cr3+ and Hg2+ from wastewater.
