摘要: 依据咪唑啉衍生物在H2S溶液中的腐蚀电化学研究结果,分析探讨了系列咪唑啉化合物在碳钢电极表面的吸附作用规律及可能的吸附状态,并建立了该类化合物可能的吸附模型.结果表明,研究的13种咪唑啉衍生物的吸附均符合Langmuir单分子等温吸附规律,为具有较大表面吸附自由能的化学吸附;这种吸附主要来自分子中不饱和五元环与金属表面的强烈作用.其可能的吸附方式是分子中咪唑环以近似平行金属表面的取向同金属表面发生相互作用,亲水支链骨架原子的奇偶性对分子的吸附作用方式具有重要影响,而憎水支链对分子的吸附过程贡献较小.

Abstract：The adsorption behaviors of some imidazoline deriva tes on the surface of mild steel electrodes was investigated based on the result s of electrochemical test in H2S solutions,a maybe adsorption model was sugges ted as well.Results show that all of 13 kinds imidazoline derivates follow Langm uir isotherm and the interaction between the inhibitor molecule and the surface of electrodes is a strong chemical action with a high Gibbs adsorption free ener gy,which is primarily from the bonding between the unsaturated five-membered nit rogen ring lying planar and the surface of metal.The of five-membered ring in im idazoline derivate molecule interacts as approximate parallel the metals surface .The number of skeleton atoms in hydrophilic chain plays an important role in ad sorption to the metal surface,as well as the changes of hydrophobic chain has a less contribution to the molecular adsorption.
