Five different techniques (analytical determination of disolved iron, Tafel line extrapolation, linear polarization method, impedance and faradaic distortion measurements) were used to evaluate the inhibiting efficiency of N-Decyl-3-hydroxy-pyridine bromide in 1 M HCl. The results obtained with the different methods wre found to agree satisfactorily. High inhibiting efficiency value was obtained at 0,1 mM concentration.

Abstract
Five different techniques (analytical determination of disolved iron, Tafel line extrapolation, linear polarization method, impedance and faradaic distortion measurements) were used to evaluate the inhibiting efficiency of N-Decyl-3-hydroxy-pyridine bromide in 1 M HCl. The results obtained with the different methods wre found to agree satisfactorily. High inhibiting efficiency value was obtained at 0,1 mM concentration.File in questo prodotto:
