摘要
采用失重法、动电位极化法、电化学阻抗谱法和计时电流法研究了硫化雷贝拉唑(RS)在1 M盐酸(HCl)中对低碳钢的缓蚀作用。RS的保护效率随浓度升高而升高，随温度升高而降低。RS在1 M HCl溶液中在低碳钢表面的吸附遵循Langmuir吸附等温线。计算并讨论了控制吸附过程的动力学和热力学参数。极化结果表明，RS在1 M HCl中是一种优异的混合型缓蚀剂。
Inhibiting Effects of Rabeprazole Sulfide on the Corrosion of Mild Steel in Acidic Chloride Solution
The corrosion inhibition effect of Rabeprazole sulfide (RS) on mild steel in 1 M hydrochloric acid (HCl) was investigated using weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and chronoamperometric measurements. Protection efficiency of RS increases with the concentration and decreases with the rise in temperature. Adsorption of RS on mild steel surface in 1 M HCl follows Langmuir adsorption isotherm. The kinetic and thermodynamic parameters governing the adsorption process were calculated and discussed. The polarization results suggest that RS performed as an excellent mixed-type inhibitor for mild steel corrosion in 1 M HCl.
