The inhibition effect of Azure A on mild steel in 1M HCl. A complete study: Adsorption, temperature, duration and quantum chemical aspects

Study of Adsorption Behavior and Inhibition Mechanism of Mild Steel in Hydrochloric Acid by a Novel Thiadiazole Derivative

“…However, the E pzc of carbon steel in presence of HMTH is more negative. In HCl solution, the HMTH molecules may exist in protonated form in equilibrium, which is consistent with the points of Sudhish, 54,55 Pongsak, 56 Demet, 57 Moretti,58 who presented that organic inhibitors can turn to -onium ions in acid solutions and then adsorb on the negatively charged metals by electrostatic forces. In addition, Haoqing Wu has presented that the E pzc of metals can be more positive when cations absorb on the surface of metal.…”

Corrosion inhibition of mild steel by two new S-heterocyclic compounds in 1 M HCl: Experimental and computational study

“…In our case, the strong interaction of inhibitors with mild steel can be attributed to the presence of heteroatoms, such as N and S, and π -electrons in the inhibitor molecules [49]. It can be seen from Table 3 …”

A new corrosion inhibitor for protection of low carbon steel in HCl solution

“…Hydrochloric acid is widely used in many industrial processes in order to remove undesirable scale and rust which leads corrosion on the iron materials. Using an inhibitor is the most efficient way to prevent unexpected metal dissolution in different acidic media [3,4]. In recent years, the use of heteroaromatic molecules and environmentally friendly compounds as an inhibitor have been gained popularity to protect the metals against corrosion [5,6].…”
