Full TextAbstract
tInhibitive performance of two thiophenol derivatives namely 4-aminothiophenol (4-ATP) and 4-aminophenol disulfide (4-APD) on corrosion behavior of 65Cu–35Zn brass in 0.5 M HNO3was investigated.Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) and also quantumchemical study were used. 4-APD showed higher efficiency at low temperatures while for higher tem-peratures the 4-ATP is more efficient. The inhibitors obey Langmuir isotherm and its adsorption is bothchemical and physical type. Quantum chemical study reveals that the benzene ring, S and N atoms canbe suitable sites for adsorption onto surface. Finally, an acceptable correlation between the theoreticaland experimental inhibitor efficiency was acquired.
