Abstract

Today, to reduce the risks of contaminants, new remediation techniques have been focused on low-cost and environmentally friendly manners. Given the frequency of access, inexpensiveness and good physical and chemical properties, biochar has a high potential for the remediation of water pollutants. In this paper, the efficiency of Chitosan Engineered biochar (Bc-Ch) and pristine biochar (Bg-Bc) prepared from Sugarcane bagasse biomass (Bg) in the Cd2+ removal in aqueous solution was investigated. To this aim, the effects of contact time, adsorbent dosage and solution pH on cadmium removal were evaluated by Adsorption Isotherms and Kinetic models. The results indicated that the Langmuir Isotherm and the pseudo-second-order kinetic model could be well fitted with the process of cadmium biosorption. The maximum Adsorption capacities of Bc-Ch, Bg-Bc and Bg, according to Langmuir model, were found to be 32/78 mg/g, 11/57 mg/g and 2/23 mg/g, respectively. For these absorbents, the pseudo-second-order kinetic model showed the best fit to the experimental Adsorption data. This study, therefore, indicated that the Chitosan Engineered biochar could be used as an effective, low-cost, and environmentally-friendly sorbent to remediate heavy metals contamination in the environment.
