“…This behavior can occur due to the strong interaction of the inhibitor with the metal surface by adsorption. Therefore, continuous adsorption of inhibitors on the surface of mild steel covers the surface area to protect the metal from attack by corrosion [6].…”

The corrosion inhibition study of 2-chloro 3-formyl quinoline was conducted for mild steel corrosion in 1 M hydrochloric acid solution at a temperature range of 303-333 K by chemical and electrochemical measurements. Inhibition efficiency increases with the increase of inhibitor concentration but decreases with increasing temperature. The polarization measurement reveals that the inhibitor acts as the mixed type and this inhibition effect is attributed to the adsorption of the inhibitor on the surface of mild steel from the bulk of the solution. The adsorption of 2-chloro 3-formyl quinoline on mild steel surface is exothermic and obeys the Freundlich adsorption isotherm. Thermodynamic parameters and activation parameters were calculated and discussed in depth. Scanning electron microscopy (SEM) micrographs were used to investigate the surface morphology of the steel sample in presence and absence of inhibitor.

“…Benzotriazole (C 6 H 5 N 3 , BTAH) has been extensively studied as an inhibitor for the corrosion of copper and many of its alloys [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], for dezincification of brass [17,18] and as additive in the etching [19], electrodeposition [20][21][22] and in the chemical mechanical polishing of copper [23][24][25]. It has also been reported to inhibit the corrosion of iron [26][27][28], cobalt [29], zinc [30], and nickel [28] and to enhance the resistance of tin bronze to oxidation in air [31].…”

A quartz crystal microbalance study of the kinetics of interaction of benzotriazole with copper

The kinetics of interaction of benzotriazole (C 6 H 5 N 3 , BTAH) with the surface of copper in salt water were studied using an electrochemical quartz crystal microbalance and X-ray photoelectron spectroscopy (XPS). Upon injecting BTAH into the electrolyte, three regions appear in the time response of the microbalance. Region I (at short time of few minutes), exhibits rapid linear growth of mass with time, which is attributed to the formation of a protective Cu(I)BTA complex. Region II reveals attachment of BTAH at a slower rate onto the inner Cu(I)BTA complex. Region III is a plateau indicating that the BTAH film attains an equilibrium mass and thickness, which increase with the concentration of BTAH. The intensity of the N1s peak in the XPS spectra increases with the time of immersion, indicating more BTAH on the surface. The results suggest a duplex inhibitor film composed of an inner thin layer of Cu(I)BTA and an outer layer of physically adsorbed BTAH which increases in thickness with time and BTAH concentration. They also offer an explanation for the much documented findings of simultaneous increase of the polarization resistance and decrease of double layer capacity with inhibitor concentration and time of immersion.

“…[4,5] The common methods to control and prevent equipment corrosion have using resistant material, using cooling water anticorrosion coating, increasing pH value of the cooling water system and adding corrosion inhibitor. [6][7][8][9] Among these methods using resistant material can protect equipment effectively, but the prime cost is too high. The technology of anticorrosion coating is complex and it is fit for local anticorrosion in the system.…”

A kind of green compound corrosion inhibitor has been made from sodium molybdate, benzotriazole, calcium gluconate, sodium polyphosphate and zinc sulfate. The inhibition capability of the corrosion inhibitor in seawater for carbon steel is carried out by weight-loss method and electrochemical method. The effect of different inhibitors concentration on the corrosion efficiency is also studied. The results show that the presence of these compounds in seawater suppresses anodic processes and when the dosage of sodium molybdate is 60mg/L, benzotriazole 60mg/L , calcium gluconate is 120mg/L, sodium polyphosphate is 60mg/L and zinc sulfate is 120mg/L , the corrosion inhibition effects of carbon steel are pretty good. Carbon steel corrosion inhibition efficiency reaches 95.53% in seawater for 15 days.
