Water pollution, driven by rapid industrialization, has become a global issue, threatening human health and ecosystems. The contamination of water sources with radioactive waste, heavy metals, toxic oxoanions led to scarcity clean drinking water. Ionic porous organic polymers (iPOPs) offer superior way for purification due their multiple binding sites ion-exchange properties, which enable them remove contaminants through electrostatic interactions efficiently. Moreover, iPOPs can be regenerated simple desorption processes reused over cycles, making cost-effective. Herein, we have synthesized chemically thermally robust (TPE-C1 TPE-C4) using one-step nucleophilic substitution reaction utilized the removal waste (iodine in vapor, aqueous, phases) along various hazardous (Cr2O72-, MnO4-, ReO4-) from via an process high uptake capacities. To best our knowledge, adsorption capacity TPE-C1 I3- (4.3 g/g) is highest field iPOPs. Both showed ultrafast kinetics (>90% within 50-150 s), kinetic constant value as 0.14 mg g-1 min-1 (for permanganate ion), enhances efficiency applicability. In presence large excess (100 times) competitive anions, remained mostly unaffected, demonstrating its excellent selectivity. Further, density functional theory (DFT) studies confirmed between oxoanions, well determined energy toward pollutants. These were recyclable up five cycles no loss maintained consistent performance across (sea, river, lake), reflecting practical For real-time use, column-based setup was prepared TPE-C1, could achieve >98% these With capacity, superfast kinetics, selectivity, facile recyclability, affordable effective solution removing wide variety pollutants advancing treatment technologies.
