Abstract
Lead is a very toxic element known to cause detrimental effects to human health even at very low concentrations. Biosorption is a versatile method for the removal of heavy metals from industrial wastewater. In this study, a novel biocarbon is produced from leaves of the medicinal plant called Acalypha indica by the sulphuric acid activation process. The biosorption capacity of the biocarbon was evaluated by considering the effect of various parameters such as pH of the solution, biocarbon dose, contact time, and initial metal ions concentration and to optimize the conditions for maximum adsorption. Batch adsorption kinetic experiments revealed that the adsorption of Pb (II) onto Acalypha indica leaves biocarbon (AIBC) involved a fast process. The adsorption process was found to be highly pH dependent, which made the biocarbon particles selectively adsorb this metal from synthetic wastewater. The biosorption results reveal that 94.8% of Pb (II) was removed from the synthetic wastewater. The optimum pH required for maximum adsorption of lead was found to be 6.0. The maximum contact time for the equilibrium condition is 150 min and the optimum biocarbon dose was 2.5g/100mL. The experimental data clearly demonstrated that AIBC can be used as a suitable adsorbent for Pb (II) ion removal from any industrial wastewate
