Abstract: Based on the weight loss method of analysis, the corrosion inhibitive properties of native banana (musa acuminate colla) extract on mild steel in 1M H2SO4 were evaluated, including the effect of inhibitor concentrations (blank, 0.2, 0.4, 0.6g/L), temperature (303.15, 313.15, 323.15, 333.15, 343.15K), and immersion time (2, 4, 6, 8, 10 hours). The results showed that a native banana extract (musa acuminate colla) inhibited corrosion in mild steel. The extracts’ inhibition efficiency increased as the concentration of the extract increased, but decreased as the temperature increased. The plant’s best inhibition efficiency was 90% at 0.2 g/L of extract at 343. 15K. The presence of native banana extract (musa acuminate colla) may be a good inhibitor because the rate of corrosion decreases noticeably. Adsorption isotherms and a comparison with known green corrosion inhibitors were used. The inhibitors’ adsorption on the mild steel surface follows the Langmuir adsorption isotherm (R2 = 0.923) and compares favorably to many documented green inhibitors
