Abstract
The removal of heavy metals from wastewater is needed as they have high toxicity that can affect human health. Activated biocarbon produced from various raw materials offers huge potential in hexavalent chromium removal from aqueous solution. In present study, the resulting biocarbon has been activated by two-step approach. Batch mode experiment was conducted at room temperature to investigate the effect of various parameters to the metal removal efficiency. The optimum contact time for hexavalent chromium removal was found to be 1 hr. The optimum biocarbon dosage was 0.125 g. The optimum initial concentration of hexavalent chromium was 100 mg/L. The optimum pH was 2. In addition equilibrium adsorption isotherm was characterized to analyze the obtained experimental data. Results showed that Langmuir isotherm type I was the best fit linearized isotherm (R2 0.9938). In conclusion, a novel and effective activated biocarbon was prepared and it has potential hexavalent chromium removal from various industrial wastewaters.
