“…However, the anodic current density values decreased significantly with increase in CC concentration, which may be due to increased surface coverage resulting in higher adsorption of inhibitor molecules. As a result, a protective film is formed on the MS surface and it reduces the surface area of MS for attack by corrosive media and retards anodic dissolution reaction [30].…”

The inhibition effect of colchicine (CC) on mild steel (MS) corrosion in 1 M HCl solution has been investigated by electrochemical techniques such as electrochemical impedance spectroscopy, potentiodynamic polarization, chronoamperometry and also by the gravimetric method. Polarization studies showed that CC acts as mixed type corrosion inhibitor. The inhibitor adsorption process in the MS/ CC/HCl system was studied at different temperatures (303-333 K). The adsorption of CC on MS surface is an exothermic process and obeys the Langmuir adsorption isotherm. Based on potential of zero charge values and quantum chemical parameters, the mechanism of adsorption has been proposed.

“…The presence of an azomethine group (-C=N-) in Schiff bases enhances their adsorption ability and corrosion inhibition efficiency [23]. Studies have shown that adsorption depends mainly on certain physicochemical characteristics of the inhibitors, such as electron density of the donor atoms, p-orbital character, and electronic structure of the molecules acting as reaction centres for the adsorption process [24,25].…”

Two new Schiff base cationic surfactants were synthesized and their chemical structures confirmed using FTIR spectroscopy. The tensioactive and thermodynamic characteristics of their solutions were determined using surface tension/log concentration plots. The protection performance of the synthesized compounds against carbon steel corrosion in 1 M HCl solution was evaluated using weight loss and electrochemical techniques. The compounds were found to be excellent corrosion inhibitors, and their efficiency increased with increasing inhibitor concentration. The mode of adsorption obeyed the Langmuir adsorption isotherm. Polarization curves showed that the two compounds were mixed-type inhibitors. The temperature dependence of the corrosion rate in the absence and presence of these compounds was studied in a temperature range of 303 to 333 K using the weight loss data. Activation parameters E a , DH a o , and DS a o were determined and discussed. In addition, the presence of a protective film on the carbon steel surface was confirmed using scanning electron microscopy (SEM).

“…The corrosion rate (C R ) was calculated using equation ( 1) (Pavithra et al, 2015): 1) was the corrosion rate of each steel specimen, A i (mm 2 ) was the surface area of steel specimen, Dt (h) was the time of corrosion reaction and Dm i (g) was the weight loss of steel specimen. The corrosion inhibition efficiency (IE) of Mannich base was calculated using equation (2) (Zhao et al, 2017):…”

Purpose In this work, a kind of Mannich base (C21H25NO) was synthesized with cinnamal aldehyde, acetophenone and diethylamine in a condensing reflux device based on the conventional method. Optimization of the inhibitor concentration was explored. Design/methodology/approach Spectral properties of this compound was investigated by FTIR, and its inhibition efficiency and mechanism on N80 steel in 20% hydrochloric acid solution were studied by weight loss measurement, electrochemical measurement (potentiodynamic polarization and electrochemical impedance spectroscopy) and surface analytical measurement (scanning electron microscope with energy dispersive spectrometer). Findings The results showed that the new inhibitor reduced the double-layer capacitance and increased the charge transfer resistance. The inhibition efficiency is 99.7% when the concentration of C21H25NO is 3%. The adsorption of C21H25NO on N80 steel surface in 20% HCl solution was found to be spontaneous and steady. Observed from the steel surface, an inhibition film was confirmed to be presented after adding inhibitor and successfully hindered the corrosive ions from reaching the bulk steel. Originality/value A new Mannich base (C21H25NO) was synthesized by cinnamal aldehyde, acetophenone and diethylamine for the corrosion prevention of N80 steel in 20% hydrochloric acid solution.
