الملخص

The inhibition of corrosion of low carbon steel (LCS) using some polyethylene glycols (PEGs) in different acidic mediums by weight loss technique was investigated. The corrosion inhibition was performed in hydrochloric acid and sulphuric acid at different acid temperatures and acid concentrations, also at various polyethylene glycol concentrations and its average molecular weights. Results obtained reveal that PEG is an active inhibitor and shows very good corrosion inhibition efficiency (IE). The IE was found to vary with acid temperature, acid concentration, polyethylene glycol's concentration and average molecular weight. Also it was found that the corrosion inhibition behavior of PEG is greater in sulphuric acid than in hydrochloric acid. The adsorption of the inhibitor on the LCS surface is in agreement with Langmuir and Frumkin adsorption isotherms. The inhibition efficiencies are increased by increase of the inhibitor's concentration and average molecular weight, decreases with an increase in the concentration and temperature of the acid.
