A new corrosion inhibitor, namely acid extract of leaves of Hibiscus sabdariffa, has been synthesized, and its inhibiting action on the corrosion of mild steel in acidic bath (1.2 N HCl and 1.2 N H 2 SO 4 ) has been investigated by corrosion-monitoring techniques. The results of the present study show that this compound has decent inhibiting property for mild steel corrosion in 1.2 N H 2 SO 4 than 1.2 N HCl. Four sorption isotherms are tested for the data, namely Langmuir, Frumkin, Florry-Huggins, and Langmuir-Freundlich isotherms; of these the Langmuir isotherm fits the data well having correlation coefficient over 0.99 in both the acid environments.

“…3a and b it can be seen that the cathodic Tafel slopes (b c ) remain almost constant with increasing inhibitor concentration. This indicates that hydrogen evolution is activation-controlled, and the addition of inhibitors does not change the mechanism of the cathodic hydrogen evolution reaction [16,17].…”

Some new triazole derivatives as inhibitors for mild steel corrosion in acidic medium

Two triazole derivatives, 3,4-dichloro-acetophenone-O-1 0 -(1 0 ,3 0 ,4 0 -triazolyl)-methaneoxime (4-DTM) and2,5-dichloro-acetophenone-O-1 0 -(1 0 ,3 0 ,4 0 -triazolyl)-methaneoxime (5-DTM) were synthesized, and the inhibition effects for mild steel in 1 M HCl solutions were investigated by weight loss measurements, electrochemical tests and scanning electronic microscopy (SEM). The weight loss measurements showed that these compounds have excellent inhibiting effect at a concentration of 1.0 9 10 -3 M. The potentiodynamic polarization experiment revealed that the triazole derivatives are inhibitors of mixed-type and electrochemical impedance spectroscopy (EIS) confirmed that changes in the impedance parameters (R ct and C dl ) are due to surface adsorption. The inhibition efficiencies obtained from weight loss measurements and electrochemical tests were in good agreement. Adsorption followed the Langmuir isotherm with negative values of the free energy of adsorption DG o ads . The thermodynamic parameters of adsorption were determined and are discussed. Results show that both 4-DTM and 5-DTM are good inhibitors for mild steel in acid media.

“…The R ct values increase with the increase in concentration of NA-KI blend, indicating an insulated adsorption layer's formation [44]. This also indicate that NA-KI blend inhibit the corrosion of mild steel in 1 M HCl solution by adsorption mechanism [45] and the thickness of adsorbed layer increases with increase of inhibitor concentration.…”

The inhibition of mild steel corrosion in HCl solution by naphthylamine (NA), KI and the synergism of KI with NA was studied at different temperatures using weight loss and electrochemical techniques. Electrochemical techniques show that the NA-KI blend is a mixed-type inhibitor. The inhibition efficiency increases with an increase in inhibitor concentration but decreases with a rise in temperature. The adsorption followed the Freundlich isotherm with negative values of DG 0 ads , suggesting a stable, and spontaneous inhibition process. The maximum blend efficiency was 95 % at high level of concentration and low level of temperature.
