In this work, the Pb adsorption and removal ability of biochar from simulated Pb(II)-contaminated wastewater, isotherms, kinetics, thermodynamics were studied. Adsorption characteristics on Pb(II) analyzed by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) scanning electron microscope with energy dispersive spectrometer (SEM-EDS). The influence pH solution, contact time...
