Biochar Derived from Palm Waste Supported Greenly Synthesized MnO2 Nanoparticles as a Novel Adsorbent for Wastewater Treatment

Water pollution with dye effluents from different industries is a broadly established environmental and health problem that needs serious attention. In this study, making use of Acacia nilotica seed extract, greenly synthesized MnO2 nanoparticles were loaded on the surface biochar derived palm waste (MnO2/PF), specific areas 70.97 m2/g. Batch experiments adopted, aiming to evaluate performance fronds, biochar, MnO2/PF adsorbents in methyl orange (MO) removal an aqueous solution. The feedstock biochars comprehensively characterized using XRD, SEM-EDX, FTIR, BET area techniques. Moreover, influences modification initial concentrations, pH, adsorbent dosage MO uptake examined. results demonstrated nanocomposite led increase efficiency by 6 1.5 times more than those fronds respectively. addition, it was found second-order kinetic model presented adsorption very well. This paper demonstrates depositing date forms novel (MnO2/PF) for solutions. Furthermore, easy synthesize under moderate conditions without need chemical capping agents, would thus be cost-effective eco-friendly.
