Abstract

The performance of inhibition mechanism and desorption behavior of the N,Ndipropynoxy methyl amine trimethyl phosphonate for iron in hydrochloride acid were investigated by means of static polarization and electrochern ical impedance spectroscopy technique.The data of the polarization curves were fitted by weak-polarization fitting technique.The results show that N,Ndipropynoxy methyl amine trimethyl phosphonate possesses high inhibiting efficiency and geometric blocking effect.It is also showed that this inhibitor obeys the Frendulich adsorption isotherm.With the increase of anodic potential,a low-frequency induce arc was observed.
