This research aims to prepare distinct, green, differential silver particles using a plant extract from the acacia tree and to study their effectiveness as a coating for resisting iron corrosion. The green synthesis method is simple, low-cost, and free of toxic chemicals.
Acacia fragrance was used as a reducing agent in the independent, dispersed synthesis of silver nitrate components. The color change of the solution indicates the formation of differential ions. Nominal characterization was performed using UV-Vis spectroscopy, revealing an absorption peak at 430 nm. FTIR spectroscopy was used to identify non-reduction groups, with peaks appearing at 3400 cm⁻¹ for the hydroxyl group and 1635 cm⁻¹ for the ligands. Carbon SEM and XRD were used to map the morphology and crystal structures. The results indicate that the group exhibits spherical and elliptical shapes, with a molecular weight ranging from 10 to 25°C, allowing for amplification.
The nano-coating was applied to iron samples to assess corrosion resistance in a seawater-like medium containing 3.5% NaCl. After immersion for 48 hours, the sample exhibited a color change, exhibiting corrosion similar to that of the uncoated sample. This demonstrated the effectiveness of the silver particle coating in mitigating the penetration of ions and the corrosive medium to the iron surface.
This study confirms that silver nanoparticles prepared using acacia plants are an effective emerging and environmentally friendly material for protecting iron metal from corrosion in industrial and environmental applications
