The Effect of Organic Compounds on the Electrochemical Behaviour of Steel in Acidic Media. A review.

This work attempts to detail selected relevant studies on the behaviour of steel in acidic media. Factors affect the inhibition efficiency of the organic compounds in acidic media were discussed; the effect of he structure, the effect of zero-charge potential and the effect of synergistic effect. Different additives of organic compounds with different active centers were used to prevent corrosion in acidic solutions. The behaviour of steel was studied in both mineral acids (sulphuric, hydrochloric and phosphoric) and organic acids.
