Therefore, treatment of wastewater contaminated by heavy metals is an important environmental concern. Manganese is the second most abundant metal in nature. In a lower concentration, Mn (II) ions and Mn (VII) ions have many valuable functions in biological systems of humans and plants. However, they become toxic at higher concentration. According to WHO, 0.05 mg/L is the maximum concentration dose of manganese admissible in drinking water. Thus, the removal of Manganese from water is imperative. In the present research work, removal of manganese (II) ions from synthetic wastewater by biocarbon generated from Acalypha indicaplant leaveswas investigated by batch adsorption technique. The biocarbon was characterized using FTIR, XRD and SEM analysis. The results suggest that, the adsorption process was relatively fast and equilibrium was established at time of 150 min. The optimum pH for manganese adsorption was 5.0 at the biocarbon dose rate of 2.5g/100mL for the maximum removal of 92.8%. The SEM micrograph shows particle grains and leaves like surfaces and FTIR analysis results shows different functional group in the biocarbon matrix such as O–H, C=O, and C=C stretching which might be responsible for the metal uptake in biosorption process.
