Abstract
The study examined the methanol extract obtained from Irsine herbstii stem as a green inhibitor for mild steel corrosion in a 1M H2S04 environment. Characterization of the extract was carried out using Fourier Transform Infrared Spectroscopy and potentiostat. Additionally, inhibition efficiency was determined through both weight loss and electrochemical measurement methods, with results indicating a maximum inhibition efficiency of 87.28%. Thermodynamic parameters further confirmed the feasibility and spontaneity of the adsorption process. Overall, the findings underscored the potential effectiveness of the inhibitor derived from Irsine herbstii alkoloid extract in mitigating mild steel corrosion in acidic environments.
