The present study is dealing with the utilization of timber plant waste biomass for the synthesis of MnO2-modified biochar (MnBC). The biochar was synthesized by the process of thermal pyrolysis of pretreated biomass with MnO2 at a high temperature (800 °C). Modification of biomass with MnO2 adds more oxygenated groups to the biochar that enhance adsorption capacity of adsorbent. The synthesized biochar material was characterized using different analytical techniques like; EDX (Energy Dispersive X-ray), SEM (Scanning Electron Microscopy), FTIR (Fourier Transform Infra-red Spectroscopy) and point of zero charge (pHZPC). The batch adsorption study was conducted for optimizing the process of As(III) adsorption via MnBC. The maximum adsorption capacity was 0.577 mg/g found at 2.5 mg/L initial concentration. The temperature study shows that the process of adsorption was endothermic.
