Abstract Three kinds of modified biochar were prepared by liquid impregnation and characterized by Fourier transform infrared spectroscope, scanning electron microscopy, N2 adsorption-desorption isotherm and elemental analyzer. Cefotaxime was selected for examining the adsorption efficiency and mechanisms of the adsorbent. The results showed that alkali modified biochar (BC-NaOH) exhibited more excellent adsorption than other biochar in 30min. The adsorption efficiency of cefotaxime by BC-NaOH was up to 83% and the data fitted the pseudo-second-order kinetic model. Thermodynamic studies showed that the adsorption process was spontaneous and exothermic. On the basis of the results of thermodynamics and adsorption influencing factors, the adsorption mechanisms of cefotaxime by BC-NaOH were hydrophobic affinity and electrostatic attraction.
