Peroxymonosulfate activation over amorphous ZIF-62(Co) glass for micropollutant degradation
ABSTRACT
Amorphous ZIF-62(Co) glass (ag-ZIF-62(Co)) was prepared and used as peroxymonosulfate (PMS) activator for the degradation of sulfamethoxazole (SMX). In the presence of 0.1 g/L ag-ZIF-62(Co) and 0.2 mmol/L PMS, approximately 98.6% of SMX with an initial concentration of 5.0 mg/L was degraded within 30 min. The main reactive oxygen species (ROS) involved were sulfate radical (SO4•-) and singlet oxygen (1O2), with concentrations of 41.1 and 171.9 μmol/L, respectively. A fixed-bed reactor packed with ag-ZIF-62(Co) was constructed for continuous SMX degradation, achieving nearly complete decontamination and 50% reduction in chemical oxygen demand over a period of 120 h. This study has paved a new avenue for exploring the potential application of metal-organic framework glasses in water purification through advanced oxidation processes.
