Abstract

In this study, the inhibition effect of 3-aminomethyl pyridine (3AMP) on mild steel corrosion behavior in acidic medium is investigated. The electrochemical techniques (electrochemical impedance spectroscopy and polarization measurements) and quantum chemical calculations were obtained. The results showed that; inhibition efficiencies increase with increasing concentration of 3AMP. The inhibition efficiency is 97% in 50 mM 3AMP containing 0.5 M HCl solution. It is found that 3AMP retards both anodic and cathodic reactions according to polarization measurements. The high inhibition efficiency of 3AMP is attributed to the high value of EHOMO (-6.937 eV), dipole moment μ (2.473 D) and low value of ELUMO (-1.049 eV). According to calculated Mulliken charges; the adsorption of 3AMP may be occurred on amine and/N terminal of molecule

Özet

Bu çalışmada yumuşak çeliğin (YÇ) asidik ortamındaki korozyon davranışına 3-Amino metil piridin'in (3AMP) inhibitör etkisi araştırılmıştır. Elektrokimyasal teknikler (elektrokimyasal impedans spektroskopisi ve polarizasyon ölçümleri) ve kuantum kimyasal hesaplamalar uygulanmıştır. Elde edilen sonuçlara göre; 3AMP'nin inhibisyon etkinliği artan 3AMP derişimi ile artış göstermiştir. 50 mM 3AMP içeren 0,5 M HCl çözeltisinde inhibisyon etkinliği %97 olarak tespit edilmiştir. Polarizasyon ölçümleri 3AMP'nin hem katodik hem de anodik reaksiyonların hızını azalttığını göstermektedir. Yüksek inhibisyon etkinliği, teorik olarak belirlenen yüksek HOMO enerjisi (-6,937 eV), dipol momenti (2,473 D) ve düşük LUMO enerjisi (-1,05 eV) ile ilişkilendirilmiştir. Belirlenen Mulliken yüklere göre; N atomları üzerindeki negatif yük sebebiyle 3AMP'nin yumuşak çelik yüzeyine adsorpsiyonunun amin ve/veya N ucundan gerçekleşebileceği düşünülmektedir
