   Kloroanilin
türevli yeni bir 2-[(2,5-diklorofenilimino)metil]fenol (CPMP) Schiff bazı literatürdeki metotlara
göre sentezlenmiş ve bu çalışmada CPMP’nin 1,0 M HCl çözeltisi içerisinde 298
K’de yumuşak çeliğin korozyonuna inhibitör etkisi, elektrokimyasal impedans
spektroskopisi (EIS), lineer polarizasyon direnci (LPR) ve potansiyodinamik
polarizasyon eğrileri yöntemleri kullanılarak araştırılmıştır. Farklı
derişimlerin zaman parametreleriyle değişimini incelemek amacıyla EIS tekniği
ile Nyquist eğrileri elde edilmiş ve bu eğrilerin de yarım elips şeklinde
oldukları görülmüştür. CPMP’nin adsorpsiyon mekanizması hakkında bilgi edinmek
amacıyla EIS tekniğiyle metalin sıfır yük potansiyeli belirlenmiştir. CPMP’nin yumuşak çelik yüzeyine adsorpsiyonunun
Langmuir adsorpsiyon izotermine uyduğu görülmüştür. Adsorpsiyon izoterminden
yararlanarak termodinamik adsorpsiyon parametreleri hesaplanmıştır.
Yumuşak çelik elektrotların yüzey morfolojileri, taramalı elektron mikroskobu
(SEM) ve yüzey morfolojisi, yüzey pürüzlülüğü ve
yüzey esnekliği hakkında önemli bilgiler veren atomik kuvvet mikroskobu (AFM)
ile incelenmiştir. EIS bulguları ile yüzey analiz sonuçları birbirini
desteklemektedir.

A NEW EXAMPLE OF MILD STEEL CORROSION INHIBITORS SYNTHESIZED FROM CHLOROANILINE: 2-((2,5-DICHLOROPHENYLIMINO)METHYL)PHENOL

Öz

   In this study according
to literature methods, a new Schiff base derived from chloroaniline
namely 2-[(2,5-dichlorophenylimino)methyl]phenol (CPMP) has been synthesized and investigated
on mild steel in 1.0 M HCl solution at 298 K by using electrochemical impedance
spectroscopy (EIS), linear polarization resistance (LPR) and potentiodynamic
polarization techniques. Nyquist curves have been obtained with the EIS and
have been found to be semi-elliptical. In order to get
information about the adsorption mechanism of CPMP, the potential of zero
charge of metal is determined by using EIS. The CPMP’s adsorption to the mild
steel surface has been seen to obey Langmuir adsorption isotherm. Thermodynamic
adsorption parameters have been calculated using adsorption isotherm. The
surface morphology of mild steel electrodes have been examined by using
scanning electron microscope (SEM) and atomic force microscope (AFM), giving
important information about surface morphology, surface roughness and surface
elasticity. EIS and surface analysis results are supported each other.
