文摘

Modified biochar supported Ag/Fe nanoparticles (Ag/Fe/MB) were successfully synthesized. Ag/Fe nanoparticles exhibited better dispersion on the surface of modified biochar. Cephalexin removal on Ag/Fe/MB occurred by simultaneous adsorption and reduction. The degradation pathway of cephalexin was analyzed.
