采用动电位极化曲线对咪唑啉缓蚀剂(MA)进行了测试,研究了在饱和CO2的1%NaCl水溶液中,缓蚀剂在碳钢表面的吸附行为,并计算了吸附反应的热力学参数,探讨了缓蚀剂的吸附模型。结果表明,该缓蚀剂是一种混合抑制型缓蚀剂,其缓蚀率随缓蚀剂浓度(3×10^-5-1.5×10^-3mol/L)的增加而增加、随温度(30℃一60℃)的升高而降低。缓蚀剂MA在碳钢表面的吸附满足E1-Awady等动力学模型,并与Flory—Huggins吸附等温线相吻合。“,”Adsorption behavior of an imidazoline inhibitor (MA) on carbon steel in CO2 saturated 1% NaClsolution is studied by potentiodynamic polarization curves. The thermodynamic parameters are calculated and the adsorption isotherm is also discussed. The results
