摘      要：The corncob hydrochar is prepared by using a stainless autoclave at 230?C for 8 *** products are characterized by elemental analyzer,Fourier Transform infrared spectroscopy(FT-IR),X-ray diffraction(XRD)and scanning electron microscope(SEM).The effects of hydrochar dosage,pH,adsorption time and phenol concentration on the adsorption performance of hydrochar are investigated by means of single-factor experimental *** on the experiments the adsorption thermodynamic and kinetics are tentatively *** results show that abundant oxygen-containing functional groups are scattered on the surface of the corncob *** adsorption kinetics of phenol on the hydrochar corresponds well with pseudo-second-order kinetic *** studies indicate that Freundlich adsorption isotherm model is much better than Langmuir model in describing the adsorption of phenol on the corncob hydrochar at 25?C-45?*** study provides scientific basis for the development of cheap and efficient adsorbents for the removal of phenols derived from oilfield wastewater.
