ResumoThe effect of thio-urea and its derivatives on the anodic dissolution of mild steel in HCl solutions has been studied. Thio-urea and N-substituted derivatives show maximum anodic polarisation at low concentrations. The anodic Tafel slope shows an abrupt change in the intermediate concentration range, i.e. 4–40 mM. This has been explained in terms of protonated species taking part in metal dissolution. S-substituted derivatives exert increasing anodic polarisation with increasing concentration.
