ABSTRACT: In this study, two nano-derivatives from nano-Graphene
oxide (GO) were synthesized. Regarding to GON and GOS by reaction GO with
2-amino ethanol and 2-marcapto ethanol respectively, the GO, GON, GOS were
characterized by FTIR, XRD and FSEM. Evaluation prepared compound to inhibitors
corrosion for Carbon steel in acidic media at (1 - 6 ppm) concentration and
different temperature 298, 308, 318, 328 K. The electrochemical technique used
Tafel plot to measure the efficiency of inhibitor. It was observed that the
corrosion rate and charge transfer of the carbon steel for the inhibitor
increase with increase of temperature and decrease with increase of the
inhibitor concentration in the same temperature. The GON had inhibition
efficiency reached 96.96% for the 6 ppm concentration at 298 K.
