The inhibition performance and adsorption behavior of (E)-2-(3-nitrobenzylidene) hydrazine carbothioamide (SB1) and (E)-2-(4-(dimethylamino) benzylidene) hydrazine carbothioamide (SB2) on mild steel corrosion in industrial water medium have been investigated by gravimetric, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The results revealed that inhibition efficiency depends on both the concentration of the inhibitors and temperature of the system. Increasing temperature reduces the inhibition efficiency of both inhibitors. Polarization studies indicated that these compounds behave as mixed type of inhibitors. The adsorption of both inhibitors was spontaneous and followed Langmuir adsorption isotherm. Thermodynamic parameters are calculated and discussed. The relation between inhibition efficiency and molecular structures of SB1and SB2was discussed by considering quantum chemical parameters. The surface adsorbed film was characterized by scanning electron microscopy (SEM).

The corrosion and adsorption behavior of leaf extract ofFuntumiaelastica(FE) on mild steel corrosion was studied in 1 M HCl using gravimetric ,electrochemical impedance spectroscopy, potentiodynamic polarization and Fourier transformed infrared spectroscopy methods, Quantum chemical calculations were performed to theoretically correlate the inhibition performance of the inhibitor with its electronic structural parameters. The gravimetric experiment revealed that the extract effectively inhibited the corrosion of mild steel even at a prolonged exposure time. The impedance and polarization results revealed that the extract inhibited both the cathodic and anodic partial reactions via the adsorption of the inhibitor on the metal/solution interface. The FTIR results revealed FE as an adsorption inhibitor. The calculated quantum chemical parameters associated with the molecular structure of FE confirmed its inhibiting efficacy.
