Porous organic polymers (POPs) are a crucial type of organic porous materials that have shown significant promise as adsorbents [3, 4]. In continuation of our research on covalent organic frameworks and porous organic polymers [5-7], hearin, a Phloroglucinol-based magnetic porous organic polymer (Ph-MPOP) was successfully created through a catalyst-free Schiff's base condensation process involving 4,4-oxydianiline and a novel trisaldehyde in the presence of magnetic nanoparticles (Fe3O4@SiO2) in dimethylformamide (DMF) under solvothermal conditions (Scheme 1). The structural properties of Ph-MPOP were characterized using different spectroscopic techniques. The prepared porous organic polymer (Ph-MPOP) demonstrated strong binding capabilities and high efficiency in adsorbing Pb(II) and Cd(II) metal ions from aqueous solutions with removal efficiencies of 97% and 95%, respectively.
