Graphene oxide nano-sheets loading with praseodymium cations: Adsorption-desorption study, quantum mechanics calculations and dual active-barrier effect for smart coatings fabrication

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, 0.00319 g of adsorbent dosage, 600 ppm of...
