Quinolone-based antibiotics commonly detected in surface, ground, and drinking water are difficult to remove and therefore pose a threat as organic contaminants of aqueous environment. We performed adsorptive removal of quinolone antibiotics, nalidixic acid and ofloxacin, using a zirconium–porphyrin-based metal–organic framework (MOF), PCN-224. PCN-224 exhibits the highest adsorption capacities for both nalidixic acid and ofloxacin among those reported for MOFs to date. The accessible metal sites of Zr metal nodes are responsible for efficient adsorptive removal. This study offers a pragmatic approach to design MOFs optimized for adsorptive removal of antibiotics.

Zr6 节点在金属-有机框架中对吸附去除水中抗生素的影响

通常在地表水、地下水和饮用水中检测到的喹诺酮类抗生素难以去除，因此作为水性环境的有机污染物构成威胁。我们使用基于锆-卟啉的金属-有机框架 (MOF) PCN-224 对喹诺酮类抗生素、萘啶酸和氧氟沙星进行了吸附去除。迄今为止，PCN-224 对萘啶酸和氧氟沙星的吸附能力最高。Zr 金属节点的可接近金属位点负责有效的吸附去除。这项研究提供了一种实用的方法来设计优化用于吸附去除抗生素的 MOF。
