Manganese impregnated biochar deriving from wheat straw were synthesized to treat heavy metal contamination. Nitrogen adsorption-desorption isotherms, scanning electron microscopy-energy dispersive X-Ray spectroscopy (SEM-EDS), and X-ray diffraction (XRD) were used to determine the characteristics of adsorbents. Batch adsorption experiments demonstrated a fit Langmuir model with the maximum adsorption capacity of 0.216 mmol g-1 for As (III) and a suitable Freundlich model for Cr (VI) respectively. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were measured to explore probable adsorption mechanisms involving As and Cr adsorption, which indicated that the Lewis acid-base interactions play a more important role in arsenic adsorption while electrostatic interaction along with the reduction Cr (VI) to Cr (III) contribute primarily to chromium adsorption.
