Abstract
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
