摘要
研究了吡咯在硫酸溶液中对铁的缓蚀作用 ,应用吸附理论及Sekine方法处理实验结果发现 ,吡咯在硫酸溶液中对铁表面产生的吸附为一取代吸附过程 ,服从Flory Huggins吸附等温式 ,并认为吸附时为平伏式取向 ,取代水分子数为2 ,求得吸附ΔG、ΔS和ΔH。讨论了吸附与缓蚀作用之间的关系。
The role and adsorption behavior of pyrrole in the corrosion inhibition of mild steel in sulfuric acid have been investigated. The experimental data have been treated with adsorption theory and Sekine method. The process was found to be a substitutional adsorption process following a Flory Huggin isotherm. The free energy, entropy and enthalpy were calculated. Relationship between adsorptionand corrosion inhibition has been discussed according to experimental results.
