Effect of some thiourea and quinoline derivatives on corrosion inhibition of Mild steel in 10% (v/v) sulphuric acid (Sp.g.1.8) was studied at 298K, 323K & 348K. Total immersion and electrochemical polarisation test was carried out. It was found from the present comparative study that thiourea derivatives have better inhibition effect than quinoline derivatives at above temperatures.


Key words
