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

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.

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

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.
