摘要

The removal of organic compounds from produced water (PW) has become a critical ecological challenge. In this work, we present the design of a Nano material, MnO2/Graphene Oxide (GO), for the efficient removal of organic pollutants from PW using a new design digital baffle batch reactor (DBBR). The MnO2 nanoparticles were synthesized and supported on prepared graphene oxide by impregnation technology (IWI) to create a highly effective Nano adsorbent material with enhanced surface area and catalytic activity. Initially, the raw material (graphite) is processed into graphene oxide nanoparticles using the Hummer technology. Subsequently, the impregnation procedure is employed to create a synthetic nano-catalyst comprising of manganese oxide in 5% amounts of the active compounds (5% MnO2/GO). The adsorbent was characterized by X-Ray Diffraction analysis (XRD) Spectroscopy (FT-IR), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET) and Field Emission Scanning Electron Microscopy (FE-SEM). The new material was steeped and was washed methodically with distilled water until it reached neutral pH. Batch treatment was carried out as a function of pH, adsorption time, temperature and dose of adsorbent. The adsorption equilibrium of organic was rapidly reached after 90 min of the adsorption time. The organic elimination was reached 94.8% and 99.8% with 0.5 g dose, 2 h with pH = 3 at 60 °C for graphene oxide and graphene oxide with MnO2 respectively. The ability of new catalyst to adsorb organic was increased then addition different quantity for adsorption time between 30 and 120 min. The models of Freundlich and Langmuir were used for the addition of experienced data, formerly it was empirical that Freundlich model was used to decide by the values got by study founded on reversion inspection. Graphene oxide branded evocatively through its high ability to adsorb organic from waste water.
