Construction of nZVI@PES metal-organic frameworks to catalyze peroxymonosulfate for removal of naproxen

Year: 2025

Type: conference-paper

Abstract: Naproxen, as one of the typical drugs and personal care products, has been widely detected in the environment due to its extensive production and use. Heterogeneous advanced oxidation technology based on persulfate activation has been more and more applied in the degradation of toxic and harmful pollutants in recent years. In particular, iron based catalytic materials are widely used in persulfate activation because of their environmental protection, low cost and high reactivity, but there are some defects in the application process such as easy oxidation and agglomeration. In this work, polymeric polyether sulfone (PES) material was introduced as organic framework, and the nZVI@PES metal-organic frameworks (MOFs) was constructed by solvent surface dissolution, phase conversion and surface reduction loading methods. Peroxymonosulfate (PMS) was further activated to degrade naproxen in aqueous environment. The synergic degradation performance of the nZVI@PES MOFs /PMS system on naproxen was evaluated.
