ASSESSMENT OF PHOENIX DACTYLIFERA SEED EXTRACT AS A GREEN INHIBITOR FOR THE CORROSION OF MILD STEEL IN AN ACIDIC SOLUTION

Metal corrosion continues to be a major problem for a variety of sectors, prompting the investigation of innovative and environmentally acceptable corrosion prevention techniques. This study examined the potential of Phoenix dactylifera (date palm) seed extract as a green corrosion inhibitor for mild steel in an acidic environment (HCl). The study thoroughly investigated the inhibitory effects of various extract concentrations (0.2-1.0 g/l) on corrosion rate and efficiency across exposure times of 168 hours using both gravimetric and Tafel polarisation methods. According to experimental findings, extract concentration and corrosion inhibition effectiveness were strongly correlated. Corrosion rates were significantly reduced at higher extract concentrations, supporting the extract's potential as a powerful inhibitor. From the results, optimum inhibiting efficiency of 96.4% with concentration of 1.0 g/l after 72 hours of exposure and 61.99% from 1.0 g/l extract were observed for gravimetric and Tafel polarization, respectively. By emphasizing the extract's capacity to adsorb components onto the steel surface and create a shield that prevents corrosion, the research also contributes to the evolving field of corrosion science through introduction of a natural and eco-friendly corrosion inhibitor.
