摘要：

A novel graphene oxide supported activated magnetic biochar (GO-AMBC) is fabricated for 17 beta-estradiol (E2) removal from aqueous solution by grafting graphene oxide (GO) and magnetite nanoparticles onto the activated biochar surface with a one-step activation, magnetization, and carbonization method. GO-AMBC is characterized using SEM, TEM, FTIR, VSM, XRD, XPS, BET surface area and zeta potential measurements. The characterization results show that GO-AMBC possesses a larger surface area and more oxygen-containing functional groups than the unmodified biochar. When the E2 initial concentrat...
