英文摘要	A novel magnetic adsorbent genipin-crosslinked chitosan/graphene oxide-SO3H (GC/MGO-SO3H) composite was prepared and used as adsorbents of environmental pollutant. The GC/MGO-SO3H exhibit typical superparamagnetic behavior. The adsorption characteristics of GC/MGO-SO3H composite to pharmaceuticals were investigated through batch experiments. The maximum adsorption capacity of ibuprofen and tetracycline increases from 113.27 to 138.16 mg/g and 473.25 to 556.28 mg/g with the increase in temperature from 298 to 313 K. The adsorption kinetics and isotherms were investigated in detail to reveal that the kinetics and equilibrium adsorptions are well described by pseudo-second-order kinetic and Freundlich isotherm model, respectively. This study has demonstrated that the GC/MGO-SO3H composite could be utilized as an efficient and with high speed.
