Abstract
In the current paper, the graphene oxide (GO) nano-sheets were benefited as a promising nano-carrier for Pr3+ cations for corrosion inhibition. The optimal experimental condition for Pr3+ cations loading was obtained. The thermodynamic and kinetic of adsorption process were studied in detail. According to the results of ICP analysis, the highest adsorption capacity of GO was found in the initial pH of 7, 0.00319g of adsorbent dosage, 600ppm of initial Pr3+ concentration, 30min contact time and at the temperature of 35°C. The loading and desorption efficiency of Pr3+ cations were characterized by series of techniques such as UV–vis, XPS, and HR-TEM. Adsorption of Pr3+ cations onto GO was simulated by quantum mechanics calculations. Electrochemical analysis showed dual active-barrier protective functioning of Pr3+ loaded GO nano-sheets in the silane matrix. The formation of a protective film was confirmed by the SEM images.
