“…The promising potential application of surfactants as corrosion inhibitors has been studied widely over the past few years. It is well known that surfactants have a tendency to associate with one another at interfaces and in solution to from aggregates [32]. The adsorption is critical to corrosion inhibition and the primary action of the surfactant functional group is to get adsorbed on the metal surface.…”

“…The adsorption is critical to corrosion inhibition and the primary action of the surfactant functional group is to get adsorbed on the metal surface. Adsorption of the surfactant molecules onto the metal surface was found to be responsible for the corrosion inhibition of the metal and in general directly related to its capability to aggregate forming micelles [32][33][34][35]. Consequently, a better understanding of the relation between the adsorption of the surfactant molecules onto the metal surface and corrosion inhibition is of great importance for both theoretical and experimental reasons.…”

“…So the inhibition efficiency increased sharply at these concentrations. At the concentration higher than CMC (10 -5 -10 -3 M), a bimolecular layer is formed on the steel surface and a very rigid barrier of surfactant molecules is established on the steel surface (Fig.2-III and Fig.3-c) (7,29,32,(36)(37)(38)(39)42). 4 shows similar pattern of corrosion for both cases but, it is more pronounced, when pH of the solution is low (0 -3) and no surfactant is present in the solution.…”

In this paper, the corrosion inhibition of cationic gemini surfactant 1,4-butan-bis-(dimethyl dodecyl ammonium bromide), in the absence and presence of halide salts (NaCl, NaBr and NaI) on steel in HCl was investigated at 20±1 ⁰C. The effects of pH, immersion time and salt concentration on the corrosion inhibition of steel were studied using weight loss, open circuit potential and electrochemical impedance spectroscopy. Inhibition efficiency was found to increase with increasing surfactant concentration. Synergistic effects between the surfactant and the salts were studied. The inhibition efficiency was found to increase with increasing salt concentration. This composite inhibitor containing gemini surfactant and halide was efficient and low-cost for steel corrosion inhibition in HCl.

Sorbitans as Corrosion InhibitorsAbstract: In the general industrial sector corrosion damage causes irreversible financial losses.As an example, in the petroleum refining industrialization process, in which electrochemical corrosive attack were correlated to several corrosive processes. Inhibitors are used in industrial scale and represent an alternative procedure to mitigate material deterioration. In this context, non ionic surfactants form a protective layer on the metal providing resistance against electrochemical damage. Sorbitan-type surfactant (Tween class) is a non-ionic corrosion inhibitor agent that have been extensively evaluated showing satisfactory results. In this present paper, the applicability and effectiveness of some sorbitans as corrosion inhibitors represent the subject of a literary review aiming the analyses of its results correlate to metallic material, temperature and corrosive media variances. In that, the applied technique, chemical structure of the surfactant and its concentrations, are herein discussed.Keywords: Corrosion inhibitor; sorbitan surfactant-type; literary review. ResumoNo setor industrial a corrosão gera prejuízos financeiros irreversíveis. Citando apenas um exemplo, a industrialização de produtos provenientes do refino do petróleo causa danos nos sistemas de dutos provenientes do desencadeamento de processos corrosivos, que se formam em função de meios eletroquímicos. A deterioração de materiais metálicos vem sendo combatida de formas variadas, o uso de inibidores de corrosão representa uma das possibilidades. Neste contexto, os tensoativos não-iônicos se destacam por formarem uma camada protetora resistente ao ataque eletroquímico. Os tensoativos do tipo sorbitanos (classe dos Tweens) são inibidores não-iônicos com eficácia comprovada, tendo sido alvo de revisão literária com destaque para suas eficácias na inibição à corrosão de materiais metálicos. Para tanto, foram apresentados resultados em função de análises das técnicas utilizadas, variações de temperatura e meio corrosivo, bem como estrutura química do tensoativo e suas concentrações.Palavras-chave: Inibidores de corrosão; tensoativos do tipo sorbitanos; revisão literária.
