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.展开更多
