Inhibition effect of sparteine isomers with different stereochemical conformations on the corrosion of mild steel in hydrochloric acid solution

This work focuses on the study of the adsorption and corrosion inhibition properties of two isomeric compounds, (+)-sparteine and (–)-sparteine, for mild steel (MS) in 1 M HCl. Weight loss experiments, electrochemical measurements, surface morphological analyses and theoretical calculation were applied to investigate and explain the effect of ‘Dextroisomer & Levoisomer’ conformations on the corrosion inhibition performance and mechanism. The...
