Abstract

The removal of dyes and bacteria from wastewater is crucial for environmental remediation and public health protection. The discharge of untreated wastewater containing dyes and bacteria can lead to water pollution, ecosystem disruption, and human health risks. In this context, we report the development of a sustainable gallic acid-based porous organic polymer (GA-azo-DADPM POP) for multifunctional water treatment applications. The polymer was characterized using 13C CP/MAS NMR, ATR-FTIR, SEM, and TEM, confirming its formation and revealing its agglomerate morphology, porous nature, and stacked sheet-like structure. The polymer exhibited a high BET surface area of 402 m2/g and a pore size distribution in the range of 2–20 nm, indicating its mesoporous nature. The adsorption studies demonstrated a maximum methylene blue dye removal capacity of 141.94 mg/g, while the antibacterial performance showed effective disinfection against E. coli. The adsorption studies followed the Freundlich isotherm and Pseudo second-order kinetic model. These results highlight the potential of GA-azo-DADPM POP for simultaneous dye removal and bacterial disinfection in wastewater treatment. In conclusion, this study demonstrates a novel, sustainable, and multifunctional material for water treatment, offering a promising solution for environmental restoration. The development of such materials can contribute significantly to the advancement of water treatment technologies, ensuring a safer and more sustainable future.
