文摘

A new α-aminophosphonic derivative was synthesized and characterized. The inhibition action was evaluated using polarization curves and EIS methods. The inhibition efficiency increase with the inhibitor concentration. Langmuir adsorption isotherm has been validated. Correlation between theoretical studies and experimental results is determined.
