“…Whereas in case of solutions having pH value of 7 and 9 the release concentration is found to be 0.584 and 0.381 mgL À1 /g of nanocon- tainer respectively. It has been observed that the more amount of inhibitor is released in acidic pH as compare to neutral and basic pH, which is in favor with the observations reported that the benzotriazole acts as a inhibitor for ferrous metals under acidic conditions [5,[56][57][58] as well as under neutral conditions [59]. The presence of large number of functional groups on polyelectrolytes are either charged or can become charged under suitable conditions (e.g: mechanical scratch or changes of local pH).…”

“…In the present study benzotriazole which contains a heterocyclic ring with three nitrogen atoms, has been used as an effective corrosion inhibitor for mild steels. It is found to be effective in acidic media [5,[56][57][58] as well as neutral media [59]. In acidic medium, benzotriazole inhibits the surface of steel from corrosion by adsorbing in its molecular or protonated form resulting in the formation of compact passive layer [60,61].…”

“…It has been reported that many heterocyclic compounds containing heteroatoms like N, O, S, have been proved to be an effective inhibitor for the corrosion of steel in the acid media [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The influence of such organic compounds on the corrosion of mild steel in acidic solution has been investigated by several authors [15][16][17]. The inhibition property of these compounds is attributed to their molecular structure.…”

Mono and bis-4-methylpiperidiniummethyl urea were synthesized, characterized and used as new corrosion inhibitors of mild steel in the acidic media. Inhibitory effect of two compounds on mild steel surface in the 1 mol$L -1 sulphuric acid has been studied by a series of techniques, such as potentiodynamic polarization, weight loss and quantum chemical calculation methods. Potentiodynamic polarization measurements showed that two inhibitors are mixed type. All measurements showed that inhibition efficiencies enhanced with increase of inhibitor concentration. This reveals that inhibitive actions of inhibitors were mainly due to adsorption on mild steel surface. Density functional (DFT) calculations have been carried out for the title compounds by performing HF and DFT levels of theory using the standard 6-31G* basis set.

“…It is well known that triazole-type compounds are good corrosion inhibitors for many metals and alloys in aggressive media [1][2][3][4][5]. For example, benzotriazole is an efficient inhibitor for iron [6] and copper [7][8][9][10][11].…”

Inhibition of mild steel corrosion in groundwater by pyrrole and thienylcarbonyl benzotriazoles

The inhibition efficiency of Zn 2? , 3-phosphonopropionic acid (3-PPA), benzotriazole (BTA) and two synthesized benzotriazole derivatives namely 1-(2-pyrrole carbonyl) benzotriazole (PCBT) and 1-(2-thienylcarbonyl) benzotriazole (TCBT) were evaluated as inhibitors for the corrosion of mild steel in ground water. The inhibition efficiencies of PCBT and TCBT in combination with Zn 2? and 3-PPA were also investigated and the results were compared with BTA. In order to study the corrosion rate and inhibition efficiency we employed potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Further characterization using Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) demonstrates the adsorption of inhibitor and the formation of corrosion products on the mild steel surface, respectively. Combination of PCBT along with Zn 2? and 3-PPA shows better corrosion inhibition efficiency than other inhibitor combinations and the individual inhibitors.
