ABSTRACT Hydrogen sulfide (H 2 S) removal from natural gas is critical due to its toxicity and corrosive nature. Adsorption one of the most effective methods, but polymeric hydrogels often exhibit limited H S adsorption capacity. To overcome this, an amine‐functionalized fly ash (FA)‐grafted polyacrylic acid (PAA) hydrogel (FA‐ g ‐PAA) was synthesized using 5 wt.% FA via solution polymerization functionalized with 30 monoethanolamine (MEA) enhance removal. Physiochemical properties performance were evaluated Fourier‐transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) analysis, thermogravimetric analysis (TGA), X‐ray diffraction (XRD). The results confirmed successful grafting MEA into PAA matrix. Due FA, morphology surface area FA‐ ‐PAA enhanced 0.04 m /g (pure hydrogel) 0.8m /g. breakthrough showed MEA‐functionalized demonstrated a superior capacity (2.0 mmol/g), significantly outperforming nonfunctionalized (1.6 mmol/g) pure (0.08 at room temperature. Molecular dynamics (MD) simulations model revealed synergistic role in enhancing adsorption. Overall, shows efficient adsorbent for industrial purification applications.
