Abstract

The inhibitive capabilities of some organic dyes namely; safranine-o (SO), thymol blue (TB) and fluorescein-Na (F-Na) on the electrochemical corrosion of mild steel in sulphuric acid solution was rapidly assessed using the gasometric technique. The results indicate that all of the studied compounds act as inhibitors in the acidic corrodent. Inhibition efficiency increased with concentration for SO and TB but decreased with concentration for F-Na. The gasometric technique provides a means for rapid assessment of inhibitor effects on corrosion rates.
