“…Thermodynamic parameter is determined based on Arrhenius equation in transition state [2]: ). By varying temperature (T), then, H* and S* may be determined from ln (i corr /T) vs 1/T curve, while change of Gibbs free energy transition (G*) is calculated according to thermodynamic equation as follows:…”

“…However, corrosion inhibitor is surface active compound which may represent organic compound, anorganic, or coordination complex compound. The sample of organic compound functioned as corrosion inhibitor is ascorbic acid, polyaniline, polyamide, imidazole, dithiocarbamate, and dithiophosphate [2][3], while inorganic corrosion inhibitor among them are natrium nitrite and natrium chromate [4]. Sample of coordination complex compound functioned as corrosion inhibitor is ZDTP [3].…”

“…Polarization technique is more profitable from sides of fast work time, high sensitivity, and efficient corrosion process measurement. Additionally, corrosion current data obtained from this technique may be used to calculate change of Gibbs free energy (G), enthalpy (H), entropy (S), and activation energy (Ea) [2,12].…”

Gemini surfactants, butanediyl 1,4-bis(dimethyl cetylammonium bromide), pentanediyl 1,5 -bis (dimethyl cetylammonium bromide) and hexanediyl 1,6 -bis (dimethyl cetylammonium bromide) from Alkanediyl-α, ω-bis (dimethyl cetylammonium bromide) series were synthesized in laboratory and were characterized by using Nuclear Magnetic Resonance (NMR) spectroscopy. The surfactants were tested as corrosion inhibitors for mild steel in 20% formic acid. The influence of surfactants on mild steel corrosion inhibition was investigated by measuring the corrosion rate of mild steel in their absence and presence by weight loss measurements, solvent analysis of iron ions into the test solution and potentiodynamic polarization measurements. The surface morphology of the corroded steel samples in presence and absence of surfactants was evaluated by using Scanning Electron Microscopy (SEM). The synthesized gemini surfactants performed as excellent corrosion inhibitor, the inhibition efficiency (IE) being in the range of 76.66-97.41%. The IE of surfactants is slightly affected by the spacer length. The IE increased with increase in surfactant concentration and temperature. The adsorption of gemini surfactants on the steel surface was found to obey Langmuir adsorption isotherm. The results of the potentiodynamic polarization studies are consistent with the results of weight loss studies.

“…Surfactants have been widely used as corrosion inhibitors for some metals and alloys in cleaning, pickling and petroleum industries processes [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The inhibiting action of surfactant compounds on the corrosion of carbon steel in aqueous media is usually related to their adsorption on the metal surface.…”

The inhibitive synergistic effect between a cationic gemini surfactant, 1,3-propane-bis(dimethyl dodecylammonium bromide) (12-3-12), and bromide ion for the corrosion inhibition of cold rolled steel in 0.5 mol L -1 H 2 SO 4 was investigated by weight loss, potentiodynamic polarization method and electrochemical impedance spectroscopy (EIS). The inhibition system composed by 12-3-12 and bromide ion is efficient. The adsorption mechanism of the 12-3-12 and bromide ion on steel in acidic medium is discussed on the basis of experimental data and an adsorption model is proposed. Adsorption of inhibitor system on the mild steel surface in acidic medium obeys Langmuir's adsorption isotherm. In addition, potentiodynamic polarization studies show that the system acts as a mixed-type inhibitor. Electrochemical impedance spectroscopy also suggests the formation of a protective layer on the steel surface by the adsorption of surfactant molecules and bromide ions.
