1 mol/L盐酸溶液中酮康唑对Q235碳钢的缓蚀行为
|
摘要
抗真菌药物酮康唑(KCZ)可作为碳钢的缓蚀剂,目前有关其吸附机制尚不明确。采用失重法、电化学阻抗谱、电化学噪声(EN)和扫描电镜,系统研究酮康唑对Q235碳钢在1 mol/L盐酸溶液中的缓蚀行为。结果表明:酮康唑对Q235碳钢的缓蚀效率η随其浓度的增加而提高,其在Q235碳钢表面的吸附作用主要为化学吸附成膜,吸附过程遵循Langmuir吸附等温式;同时,酮康唑对Q235碳钢的缓蚀效率与Q235碳钢的活性反应能量具有相反的变化方向,因此可以采用EN技术实现对缓蚀剂保护效果的原位无损监测。
Various methods such as weight loss test,electrochemical impedance spectroscopy,electrochemical noise( EN) measurement and scanning electron microscope were conducted to systematically investigate the inhibition behavior of ketoconazole( KCZ) on Q235 mild steel corroding in 1.0 mol/L HCl solution. Results showed that the inhibition efficiency( η) increased with the increasing KCZ concentration,and the adsorption mechanism on Q235 steel was chemisorption,which followed the Langmuir isotherm. In addition,the variation trend between ηand active reaction energy Eaof Q235 mild steel with the increase of KCZ concentration was opposite,and therefore EN technique could be used effectively to in-situ monitor the protection effect of an inhibitor.
