【摘要】 采用稳态极化曲线和交流阻抗测试技术研究了环己基二炔氧甲基胺氨基三甲撑膦酸盐在盐酸介质中的缓蚀作用机理和阳极吸脱附行为。对极化曲线实验数据按弱极化曲线模式进行拟合。研究结果表明，环己基二炔氧甲基胺膦酸盐在盐酸介质中的缓蚀机理为覆盖效应。吸附等温式符合Ｆｒｅｕｎｄｌｉｃｈ等温式。随缓蚀剂的脱附，阻抗谱在低频区出现感抗弧，且随脱附的进行而增大。更多还原

【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.更多还原
