“…28,29 In this job, the ¹26.76 KJ/mol of ÁG 0 ads value means the adsorption of BTAOH on mild steel surface is physisorption. [32][33][34] And this value is similar to the respective result in the job of Chen et al (¹30.54 KJ/mol). 19 However, the IE of BTAOH for mild steel is not so significant than other heterocyclic organic compounds, for example, dithiazolidines, 35 thiadiazole derivatives 6 and so on.…”

The inhibition ability of 1-hydroxy benzotriazole (BTAOH) for mild steel in HCL solution (1 mol/L) had been investigated in this manuscript. The inhibition efficiency of BTAOH showed a maximum value around 48% at 303 K, with the concentration 1.5 × 10 −3 mol/L. The physical adsrobed BTAOH molecules are more stable attached onto the mild steel surface than the corrosion products. The similar free energy of adsorption (ΔG 0 ads ) but much lower IE were ascribed to the thicker but less compact film constructed by the zig-zag H-bond connected BTAOH polymers. According to the effects of concentration and temperature on the adsorption behavior of the BTAOH, we had calculated the ΔG

“…In the present study, DG ads values for PMN, MMN, NBT and MBN are found to be in the range -33.95 to -36.97, -34.08 to -37.07, -34.83 to -37.86 and -34.97 to -38.04 kJ mol -1 in the temperature range of 30-60°C, respectively indicating that the adsorption is the combination of both physisorption and chemisorption [40][41][42][43].…”

Background A new class of nicotinamide derivatives viz., N-((1H-pyrrol-2-yl)methylene)nicotinamide, N-((methyl-(phenyl)amino)methylene)nicotinamide, N-nicotinoylbenzimidothioic acid and N-(4-(methylthio)benzylidene)nicotinamide have been synthesized and their corrosion inhibition effect on mild steel in 0.5 M HCl was investigated by mass loss, Tafel polarization technique and AC impedance measurements. Results The inhibition efficiency of the inhibitors on mild steel in 0.5 M HCl has been studied based on concentration, time interval and temperature. Potentiodynamic polarization studies showed that all the examined inhibitors suppress both anodic and cathodic process and behave as mixed type of corrosion inhibitors. Conclusions The adsorption of all the inhibitors was found to obey Langmuir isotherm model. Electrochemical impedance data revealed that polarization resistance (R P ) increases and double layer capacitance (C dl ) decreases as the concentration of the inhibitors increases. FTIR, EDX and SEM analyses were performed to study the film persistency of the inhibitors.

“…Generally, values of −ΔG ads around 20 kJ mol −1 or lower are consistent with electrostatic interaction between the charged molecules and the charged metal (physisorption), those around 40 kJ mol −1 or higher involve charge sharing or transfer from organic molecules to the metal surface to form a coordinate type of bond (chemisorption) [17,18]. On the other hand, Bayoumi and Ghanem [19] reported that the adsorption of naphthalene disulphonic on the mild steel is chemisorption (−ΔG ads =28.47 kJ mol −1 ). Thus, the obtained values of ΔG ads here suggest that the chemisorption of 2-HBTA occurred onto the low carbon steel surface in industrial water.…”

This work was carried out to study the inhibition mechanism of volatile corrosion inhibitors (VCIs) such as 2-hydrazinobenzothiazole (2-HBTA) on the corrosion of low carbon steel in industrial water by using polarization and mass loss measurement. It was found that 2-HBTA revealed good performance as inhibitor for low carbon steel corrosion in industrial water. After some time, the performance decreased due to the volatility of these kinds of inhibitors away from the open system unlike the closed system. The experimental data indicated that the inhibitive performance of 2-HBTA for low carbon steel was improved with increasing of concentration up to the critical concentration (4.24×10 −3 M). The adsorption behavior of 2-HBTA was found to obey Langmuir's adsorption isotherm. The thermodynamic parameters of adsorption process and activation energy were obtained from polarization technique. Scanning electron microscopy (SEM) was performed to characterize the film formed on the surface. Box-Wilson statistical method was employed to correlate the results obtained, and the optimization of fluid velocity, temperature and concentration of inhibitor by using Box-Wilson statistical method was evaluated.
