Hickory biochars were obtained through slow pyrolysis under 350 8C, 450 8C, and 600 8C. Multiplecharacterization techniques were used to characterize the biochars and showed pyrolysis temperatureaffected their O/C ratios, surface areas, cation-exchange capacities, zeta potential, surface acidic groups. As the result, the biochars showed different adsorption ability to Pb(II) and methylene blue in aqueoussolutions, which was due to the important roles of the physicochemical properties of the biochars incontrolling the sorption processes. This work provided a comprehensive evaluation of biochars, and thusexpanded on previous research on effects of pyrolysis temperature on biochar properties.
