Abstract

In this study, electrochemical and theoretical approaches were used to explore the inhibitory characteristics of 2-ethyl-4-methyl-1,3-thiazole-5-carboxylic acid (2E4MT5C) against the corrosion behavior of mild steel in 0.5 M HCl solution. During a 7days immersion time in HCl solutions with and without 5 mM 2E4MT5C, electrochemical impedance spectroscopy (EIS) measurements and polarization curves were obtained. The adsorption equilibrium constant and adsorption free energy were determined by drawing the adsorption isotherm using the data obtained from the EIS measurements performed for 1 hour immersion time in HCl solutions containing 2E4MT5C at different concentrations (0.5; 1; 3 and 5 mM).To demonstrate the relationship between molecular structure and electrochemical behavior, and to study the adsorption process, experimental data were compared to theoretical parameters. According to the results obtained for the 1-hour immersion time, the resistance values for MS were 39 ..cm2 in the absence of 2E4MT5C and 195,3 .cm2 in the presence. According to the results obtained for the 7-days immersion period, the resistance values for MS are 9.8 .cm2 in the absence of 2E4MT5C and 38.3 .cm2 in the presence. Theoretically calculated EHOMO and ELUMO values are -6.89 eV and -1.78 eV. The dipole moment was determined as 5.96 Debye. According to the findings, 2E4MT5C offers significant protection against mild steel corrosion.

Abstract

Bu çalışmada, 2-etil-4-metil-1,3-tiyazol-5-karboksilik asitin (2E4MT5C) 0,5 M HCl çözeltisinde yumuşak çeliğin (MS) korozyon davranışına karşı inhibitör özellikleri elektrokimyasal ve teorik yöntemlerle araştırılmıştır. 7 günlük daldırma süresi boyunca 2E4MT5C içermeyen ve 5 mM 2E4MT5C içeren HCl çözeltilerinde elektrokimyasal impedans spektroskopi (EIS) ölçümleri ve polarizasyon eğrileri elde edildi. Farklı derişimlerde (0,5; 1; 3 ve 5 mM) 2E4MT5C içeren HCl çözeltilerinde 1 saatlik daldırma süresi için gerçekleştirilen EIS ölçümlerinden elde edilen veriler vasıtasıyla adsorpsiyon izotermi çizilerek, adsorpsiyon denge sabiti ve adsorpsiyon serbest enerjisi belirlendi. Moleküler yapı ile elektrokimyasal davranış arasında ilişki kurmak ve adsorpsiyon mekanizmasını araştırmak için deneysel sonuçlar teorik parametrelerle karşılaştırıldı. 1 saatlik daldırma süresi için elde edilen sonuçlara göre, MS için polarizasyon direnci değerleri 2E4MT5C yokluğunda 39 .cm2 ve mevcudiyetinde ise 195,3 .cm2 dir. 7 günlük daldırma süresi için elde edilen sonuçlara göre, MS için direnç değerleri 2E4MT5C yokluğunda 9,8 .cm2 ve mevcudiyetinde ise 38,3 .cm2 dir. Teorik olarak hesaplanan HOMO ve LUMO değerleri -6,89 eV ve -1,78 eV dir. Dipol moment 5,96 Debye olarak belirlenmiştir. Elde edilen sonuçlara göre 2E4MT5C'nin yumuşak çelik korozyonuna karşı etkin koruma sağladığı görülmüştür.
