Abstract

The article focuses on the synthesis and characterization of a porous, low-cost, nitrogen-rich melamine-based polymer (MB) functionalized with 5-bromo-2-thiophenecarboxaldehyde via a one-pot polycondensation method. This hyper-crosslinked polymer exhibits high thermal stability, mesoporous structure, and multiple functional groups, enabling selective detection of mercury ions (Hg²⁺) and sodium hypochlorite (NaOCl) in aqueous solutions, as demonstrated by UV-Vis absorption studies. Characterization techniques including X-Ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), differential thermal analysis (DTA), X-Ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and Brunauer-Emmett-Teller (BET) analysis confirmed the polymer’s chemical structure, morphology, porosity, and stability. The study highlights MB’s potential as an economical and effective sensor material for environmental monitoring of heavy metal ions and reactive oxygen species.
