Influence of electron releasing groups in benzylidene thiocarbohydrazide and their synergetic effect with iodide ions on acidizing corrosion inhibition of carbon steel in 15% HCl using chemical and electrochemical methods has been studied. Tafel polarization measurements indicate that these compounds act as mixed-type inhibitors. The adsorption of these compounds obey Langmuir adsorption isotherm and the thermodynamic parameters are also calculated to explain their inhibitive action. The increase in synergism parameter (S_θ) indicates that the inhibition efficiency is improved in the presence of the iodide ions. Further, the density functional theory is used to validate the experimental results.

亚苄基硫代碳酰肼中电子释放基团的影响及其与碘离子的协同作用对碳钢在15% HCl溶液中酸化缓蚀的影响——实验与理论方法

采用化学和电化学方法研究了亚苄基硫代碳酰肼中电子释放基团的影响及其与碘离子的协同作用对碳钢在15% HCl中酸化缓蚀的影响。Tafel 极化测量表明这些化合物作为混合型抑制剂。这些化合物的吸附服从朗缪尔吸附等温线，并且还计算了热力学参数来解释它们的抑制作用。协同参数（S _θ）的增加表明在碘离子存在下抑制效率提高。此外，密度泛函理论用于验证实验结果。
