Abstract A novel magnetic epigallocatechin-3-gallate-modified Fe3O4 nano-catalyst (EGCG@Fe3O4) was fabricated, characterized, and tested to active peroxymonosulfate (PMS) for the degradation of sulfadiazine (SD) in solution. The results illustrate that EGCG@Fe3O4 exhibits a higher catalytic ability than unmodified Fe3O4 toward SD degradation. Both SD removal and PMS decomposition clearly follow the pseudo-first-order kinetic pattern in the EGCG@Fe3O4/PMS system. When the catalyst and PMS… Expand
