Abstract The feasibility of employing a new alkali-activated clay mineral biochar composite produced from simultaneous oxygen-limited pyrolysis of peanut shells biomaterials and spent bleaching earth (SBE) was explored. Product materials were characterized by Brunnet-Emmett-Teller (BET), X-ray fluorescence spectrometer(XRF), scanning electron microscope(SEM), X-ray diffractometer(XRD) and Fourier transform infrared spectrometer(FTIR) . The influence of variables like initial metal loading, pH, contact time, and temperature on the adsorptive removal of Pb(Ⅱ) from water was studied, respectively. The adsorption capacity was 184 mg/g with 92.4% of Pb(Ⅱ) removal at 25 ℃,with contact time of 50 min, solution concentration of 100 mg/L and pH=6. Pseudo-second-order kinetics was the most suitable model for the removal of Pb(Ⅱ), while the equilibrium agreed with Langmuir isotherms. The interaction of SBE/C with the wastewater was endothermic interaction. The Pb(Ⅱ) removal rate of SBE/C could still reach about 84.6% even after five run times, which implied SBE/C possessed reusability.
