Abstract

Glucose is an organic molecule whose characteristics are corrosion inhibitors. The adsorption and inhibitory effect of glucose on copper surfaces in alkaline (pH 8.0) Chloride solutions were investigated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and scanning electron microscopy (SEM). The data obtained indicate that glucose behaves as a mixed-type inhibitor by physically adsorbing onto copper surfaces according to the Langmuir isotherm. The inhibition activity of glucose increases with increasing the concentration of glucose.
