Abstract
and a removal efficiency of 50.35%. The Pseudo-second-order model and Langmuir adsorption isotherm model could preferably describe the adsorption process, indicating the adsorption of lead was monolayer accompanied by chemical adsorption. It can be concluded that co-pyrolysis of biomass and polyethylene and modification may be favorable to enhance the properties of biochar. In addition to syngas and bio-oil from co-pyrolysis, biochar may be a valuable by-product for commercial use, which can be used to remove heavy metals in water, especially stem-pith biochar.
