This study investigated the Pb(II) and Cd(II) sorption from aqueous solution by oily sludge-derived char (OSDC) prepared at different pyrolysis temperatures and chemical activation. The maximum Pb(II) sorption capacity for OSDC at pyrolysis temperature of 500 °C (OS50 was found as 351.48 mg/g, which was greater than that of OSDC produced at other temperatures. Post-sorption characterizations using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and sequential extraction test indicated the precipitat
