Abstract

Inhibition of corrosion of mild steel material in sulphuric acid medium has been tried with many synthetic and green inhibitors. Each inhibitor has its own merits and limitations. The present study aims at the synthesis of 8-Hydroxy Quinoline (8HQ) and Pyridine N-Oxide (PyNO) and the study of their inhibition behaviour on the corrosion of mild steel in 2 N sulphuric acid. The inhibition behaviour of the synthesised compounds was studied by subjecting to weight loss measurements, polarisation studies and electrochemical impedance spectra (EIS) for the assessment of their performance. The studies were made with 2 N sulphuric acid as the corroding medium, but with the inhibitor concentration in the range of 50 -350 ppm. The results revealed that the inhibitors studied perform better in the medium and function by the mechanism of adsorption onto the metal surface.
