THE EFFECT OF CORROSİON OF 5-(4-Dimethylaminobenzyliden)-rhodanin on MİLD STEEL

Abstract

The inhibition effect of 5-(4-Dimethylaminobenzyliden)-rhodanin (D-Rh) molecule on mild steel corrosion has been investigated in 0.5 M H₂SO₄ solution using help with electrochemical impedance spectroscopy, linear polarization resistance, chronoamperometry and potentiodynamic polarization techniques. The experimental result show that the inhibitor efficiency increases with increasing inhibitor concentration. The adsorption isotherm is suitable with Langmuir. The Ea are calculated.

YUMUŞAK ÇELİĞİN ASİDİK ORTAMDAKİ KOROZYON DAVRANIŞINA 5-(4-Dimetilaminobenzyliden)-rodanin MOLEKÜLÜNÜN ETKİSİ

Abstract

5-(4-Dimetilaminobenzyliden)-rodanin (D-Rh) molekülünün, yumuşak çeliğin korozyonuna inhibisyon etkisi 0,5 M H₂SO₄ çözeltisinde, elektrokimyasal impedans spektroskopisi, lineer polarizasyon direnci, kronoamperimetri ve potansiyodinamik polarizasyon eğrilerinden yararlanılarak araştırılmıştır. Deneysel sonuçlar inhbisyon etkinliğinin D-Rh’ın derişimi ile artığını göstermiştir. Adsorpsiyon izotermi Langmuir adsorpsiyon izotermine uymaktadır.  D-Rh molekülü için aktivasyon enerjisi hesaplanmıştır.
