The purpose of this study is to investigate the effect of an organic compound inhibitor, namely "Methyl
Carbazodithoate ", on the corrosion of low carbon steel (mild steels) in 2.0 M Sulphuric acid (H₂SO₄) solution
by weight loss measurements and over the temperature range 30 - 50 °C. The effects of organic compound
inhibitor concentration on the corrosion rate of low carbon steel have been found to increase with inhibitor
concentration (7.5x10⁻⁴ - 4.0x10⁻³) M at both temperature 30 °C and 50 °C. A detailed analysis of the
experimental data was performed to determine the best models of isothermal equilibrium data sets for the used
inhibitor. The results were fit to all used adsorption isotherms including; Langmuir isotherm and Temkin
isotherm, while a slight improvements were observed when using an organic inhibitor at temperature of 50 °C.
The standard free energies of adsorption ΔGads are calculated. Finally, the inhibition efficiencies of "Methyl
Carbazodithoate" obtained from the all various measurements were in good agreement.
