The investigation on the efficiency of three organic derivatives was done as inhibitors for carbon steel using electrochemical methods at four temperatures (303, 313, 323, and 333 K) and 100 ppm. The results showed that these prepared compounds gave good efficiencies at experimental conditions by adsorption process and they act as mixed-type inhibitor, the data of corrosion were measured and debated. Using SEM, the inhibited surface of specimens was characterized. In addition, for display the interaction between these compounds and the metallic surface, the Fourier transform infrared spectra was used. In addition, the activity of antibacterial of the inhibitors against some types of bacteria was tested.
