Main Article Content
Abstract
The study was designed to investigate the corrosion inhibition potential of beta carotene for mild steel in acidic medium. Gravimetric, gasometric and polarization methods were used for the study. The results obtained indicated excellent corrosion efficiencies from all the used monitoring methods. Correlation between results obtained from different methods were also excellent. Carotene acted as an adsorption inhibitor. Its adsorption is exothermic, spontaneous and reflected physiosorption adsorption mechanism. Langmuir and Temkin adsorption isotherms best fitted the adsorption characteristics of the inhibitor. Computational chemistry investigation revealed semi empirical values that compares favourably with those of excellent corrosion inhibitors. The sites for electrophilic and nucleophilic attacks resided in the C(35) and C(14) atoms respectively.
