The inhibitory propensity of the Piper nigrum Linn. seeds for acid corrosion of aluminium alloy (AA1100) was investigated employing weight loss method. Kinetic and adsorption parameters were calculated. The inhibition efficiency was found to increase with increase in inhibitor concentration. The experimental data were fit in to the El-Awady’s thermodynamic–kinetic model. Surface analysis was carried out by FT-IR to ascertain the anti-corrosive property of the inhibitor.
