Inhibitive efficacy of Alstonia boonei leaves extract to combat acid corrosion of copper at the room temperature (30C) was investigated using chemical method. Various corrosion parameters, viz. corrosion rate (corr), inhibition efficiency ( %IE), adsorption equilibrium constant (Kad), degree of fractional surface coverage (q) were evaluated using experimental data. Maximum inhibition efficacy was observed as 93.2 % at 1.081g/L of Alstonia boonei extract and its adsorptive propensity was assessed by Quantum Chemical Analysis. The characterization techniques, viz. FT-IR, UV-Vis spectroscopy and surface morphological analysis tool (SEM) were used to endorse the results. The entire study shows that the Alstonia booei extract can be a promising greener anti-corrosive agent for copper in acid media.
