The complex of CTAB and NaCl acts as a mixed type inhibitor, which mainly inhibits cathodic reaction. The adsorption of complex follows with the Langmuir adsorption isotherm. 研究表明:CTAB与NaCl的混合物表现为阴极为主的混合型缓蚀剂,混合物的吸附符合Langmuir等温式。
A Discussion on Chemical Reaction Isotherm 关于化学反应等温方程式推导的讨论
Results showed that inhibition mechanism of MODA was geometry covering effect. It enhanced activation energy of corrosion reaction after it adsorped on metal surface. The adsorption pattern was obedient to Flory-Huggins adsorption isotherm. 结果表明:MODA的缓蚀作用机理系几何覆盖效应,它在金属表面吸附成膜后,提高了腐蚀反应的活化能,其吸附规律符合Flory-Huggins吸附等温式。
