The metal corrosion inhibition efficiency of a novel synthesized cationic gemini surfactant (SCGS), namely, 4,4′-(((1E,5E)-pentane-1,5-diylidene)bis(azanylylidene))bis (1-dodecylpyridin-1-ium) bromide, was studied in acidic medium by three techniques. The achieved results displayed the inhibition efficiency of the metal corrosion that was elevated by increasing both the SCGS's concentration and the applied temperature values. Furthermore, it was noticed that the charge transfer resistance value was elevated; however, the constant phase element was decreased with increasing the SCGS concentrations. The SCGS regards an excellent and mixed-type corrosion inhibitor. The adsorption of SCGS has agreed the Langmuir's adsorption isotherm and was related to physisorption and chemisorption.

新型合成阳离子双子表面活性剂（SCGS）的金属腐蚀抑制效率，即4,4'-（（（（1E，5E）-pentane-1,5-diydenne）bis（azanylylidene））bis（1-dodecylpyridin-通过三种技术在酸性介质中研究了溴化1-ium）。所获得的结果表明，通过同时增加SCGS的浓度和所施加的温度值，可以提高金属腐蚀的抑制效率。此外，注意到电荷转移电阻值升高；电荷转移电阻值升高。然而，随着SCGS浓度的增加，恒定相元素减少。SCGS是一种出色的混合型缓蚀剂。SCGS的吸附与Langmuir的吸附等温线一致，并且与物理吸附和化学吸附有关。
