摘要
采用静态失重、电化学阻抗谱、动电位扫描等测试方法研究荠菜提取液及其与KI的复配缓蚀剂对Q235在1 mol/LHCl介质中的缓蚀协同行为及温度、浓度和时间因素的影响。结果表明,单独荠菜提取液和复配KI后的缓蚀剂均为混合抑制型缓蚀剂,且二者的缓蚀率均随缓蚀剂浓度、温度的升高和时间的延长而增大。复配碘离子后缓蚀率显著增大,协同效应因子(S_1)分析出二者表现出协同效应。热力学和动力学参数分析出缓蚀剂的化学吸附机理,且在Q235表面的吸附符合朗缪尔吸附等温式。
The inhibition effect of Capsella bursa-pastoris extracts(CBE) and its synergistic effect with KI(CBEK) for Q235 mild steel in 1 mol/L HCl solution were studied by electrochemical measurements.Both CBE and CBEK can serve as eco-friendly,mixed-type inhibitors,and the inhibition efficiency increases with the concentration,temperature and immersion time.The synergistic parameter(SI) indicates a cooperative mechanism between the iodide anions and CBE molecules at lower temperature.The associated thermodynamic and kinetic data suggest the presence of CBEK on metal surface mainly through chemisorption at higher temperature.The adsorption processes follow Langmuir isotherm.
