Corrosion inhibition of API5L X60 steel in sulfuric acid using gum arabic
The aim of this research is the evaluation of inhibitory efficiency of Gum Arabic (GA) against the corrosion of API5L X60 pipeline steel in H2SO4 (0.5M) media, using mass loss measurement and electrochemical methods. The results show that inhibition efficiency increases with inhibitor concentration to attain 83% at 4 g/L of GA. Polarization curves reveal that GA acts as a mixed-type inhibitor in sulfuric acid. The adsorption of GA on pipeline API 5L X60 steel surface obeyed the Langmuir adsorption isotherm. Gibbs free energy of adsorption indicated that the adsorption process is spontaneous and the molecules adsorbed on the metal surface by the process of physical adsorption.
期刊介绍：
The journal Revue Roumaine de Chimie (Roumanian Journal of Chemistry) was founded in 1956 under the name Revue de Chimie. Acad. R. P. R. from 1964, the title was modified in Revue Roumaine de Chimie (preserving the numbering of the volumes started in 1956). In 1997, the English translation of the title – Roumanian Journal of Chemistry – was also included on each issue.
