Summary: | The relationship between structure and corrosion inhibition of a series of twenty-eight quinoline and pyridine derivatives has been established through the investigation of quantum descriptors calculated with PBE/6–311 + + G** method. A quantitative structure–property relationship (QSPR) model was obtained by examining these descriptors using a genetic algorithm approximation method based on a multiple linear regression analysis. The results indicate that the efficiency of corrosion inhibitors is strongly associated with hardness (
η
), minimal electrostatic potential (ESP
min
), and volume (
V
) descriptors. Furthermore, the validity of the proposed model is corroborated by an adsorption study on an iron surface Fe(110). |
