Abstract Wheat straw biochar was prepared using a low-temperature pyrolysis device, and the biomass char was characterized by SEM, FTIR, and BET, respectively. Through the research of isothermal adsorption process, it was found that the adsorption of Pb(Ⅱ) by wheat straw biochar accorded with Langmuir model, and it was a spontaneous endothermic process. The investigation of adsorption kinetics found that the pseudo-second-order kinetic model can well describe the process of wheat straw biochar adsorption of Pb(Ⅱ). This adsorption process is a complex process and may be controlled by surface adsorption and intra-particle diffusion together with chemisorption.

Key words： wheat straw biochar adsorption Pb(Ⅱ)
