Investigation of Temperature Correlations on Corrosion Inhibition of Carbon Steel in Acid Media by Flower Extract

Öz

Temperature relationships of Vigna subteranea flower (VSFE) extract on the corrosion of carbon steel in 2.0 M H2SO4 at 303-323 ˚K was studied by weight loss method. The obtained results show that VSFE extract acts as inhibitor for carbon steel in H2SO4 solution. The inhibition efficiency was found to increase with increase in VSFE extract concentration but decreased with acid concentration and temperature, which is suggestive of physical adsorption mechanism although chemisorption may play a part. The adsorption of VSFE onto the carbon steel surface was found to follow the Langmuir adsorption isotherm. The correlation coefficient (R²) ranging from 0.9992 ≥ R² ≥ 0.9715 was obtained. Both kinetic parameters (activation energy, pre-exponential factor, enthalpy of activation and entropy of activation) and thermodynamics of adsorption (enthalpy of adsorption, entropy of adsorption and Gibbs free energy) were evaluated and discussed from the effect of temperature on the corrosion and inhibition processes.

Vigna subteranea çiçeği (VSFE) ekstraktının karbon çeliğinin korozyonunda sıcaklık ilişkisi 303-323 ˚K’de 2 M H2SO4 kullanılarak ağırlık kaybı metodu ile incelenmiştir. Elde edilen sonuçlara göre, VSFE karbon çeliği için H2SO4 çözeltisinde inhibitor gibi davranmaktadır. İnhbisyon veriminin VSFE ekstraktı konsantrasyonunun artışı ile arttığı, asit konsantrasyonu ve sıcaklıkla azaldığı belirlenmiştir. Buna göre, bir kısım kemisorpsiyon söz konusu olsa da, fiziksel adsorpsiyon mekanizması baskın bulunmuştur. VSFE’nin karbon çeliği yüzeyinde adsorpsiyonunun Langmuir adsorpsiyon isotermine uyduğu belirlenmiştir. Korelasyon katsayısının (R²) 0.9992 ≥ R² ≥ 0.9715 aralığında olduğu bulunmuştur. İki kinetik parametre de (aktivasyon enerjisi, pre-eksponansiyel faktör, aktivasyon entalpisi ve aktivasyon entropisi) ve adsorpsiyon termodinamiği (adsorpsiyon enthalpisi, adsorpsiyon entropisi ve Gibbs serbest enerjisi) değerlendirilmiş ve inhibisyon prosesi ve korozyona sıcaklık etkisi açısıdan tartışılmıştır.
