ZIF-8/ZIF-67 derived carbon for efficient removal of antibiotics in aqueous solution

Abstract

In this paper, ZIF-8/ZIF-67 derived carbon (ZDC) was synthesized by surface modification technology and calculation process subsequently. In order to evaluate the feasibility of ZDC for antibiotic removal, the adsorption experiments were carried out by three typical antibiotics: tetracycline (TC), norfloxacin (NFO) and ofloxacin (OFO). The results showed that the maximum adsorption capacities of TC, NFO and OFO based on ZDC were 543.48, 239.8 and 340 mg/g, respectively. The adsorption capacity of ZDC was better than that of many other similar adsorbents, which is a potential adsorbent for antibiotic removal in the contaminated water.
