Efficient adsorption of antibiotic from aqueous solution is a serious task for public health and environmental protection. In this work, a high surface area metal-organic framework was employed for antibiotic adsorption. To this end, at first metal-organic framework was synthesized and then, characterized using the Brunauer-Emmet-Teller (BET) and X-ray diffraction (XRD) analyzes. After that, adsorption experiments were performed to examine the capability of the synthesized adsorbent for adsorption of antibiotic. The surface area of the absorbent was obtained to be 1300 m2g-1 using the BET analysis. In addition, metal-organic framework had an excellent adsorption capacity of 305.8 mg g-1. Also, the adsorption experiments indicated that the adsorption rate was high at the lowest tested concentration (40 mg L-1) so that the adsorption kinetic reached equilibrium after 60 min. Kinetics data were best fitted with pseudo second-order model. Moreover, isothermal data were best fitted with Langmuir model.
