Xylopia aethiopica EXTRACT AS GREEN AND ECO-FRIENDLY CORROSION INHIBITOR AND ITS QUANTUM CHEMICAL ANALYSIS.

This work examines the corrosion inhibitory behavior of Xylopia aethiopica stem bark and root extracts respectively on mild steel in 2M HCl solution their quantum chemical analysis using gravimetric technique computational modeling. The rates coupons blank solutions were found to increase with concentration corrodent, period immersion rise temperature. On other hand, rate decreased acid containing test decrease became more pronounced concentrations respectively. indicates that inhibited inhibition efficiency increased extract concentrations. is attributed adsorption constituent molecules surface, forming a film layer protects metal surface from corrodent. Results proved that, 3-dimethyl- 1-vinylcyclohexene among compounds would be most likely organic compound share electrons for possible bond. fitted into Langmuir isotherm slope values 0.86 0.98 respectively, regression correlation (R2) 1.0 0.99
