This research investigated the corrosion inhibition potential of Mangifera Indica Peel Extract (MIPE) for mild steel in a 1 M HCl solution. The study explored the effects of extract concentration, solution temperature, and immersion time on the inhibition potential of MIPE using weight loss measurements at extract concentrations of 0, 1.0, 1.5, and 2.0 g/L, temperatures of 303 K and 323 K, and immersion times of 1, 2, 4, 6, and 8 h. Experimental results showed that MIPE significantly reduced the corrosion rate of mild steel, with maximum inhibition efficiency reaching 97.26% and 94.83% at 2.0 g/L MIPE concentration and solution temperatures of 303 K and 323 K, respectively. The uninhibited mild steel experienced increased corrosion rates with rising temperatures and longer immersion times. The inhibition efficiency of MIPE improved with higher extract concentrations and immersion periods. These findings underscore the potential of MIPE as an effective and environmentally friendly corrosion inhibitor in acidic environments.
