The inhibitive effect and adsorption behavior of 2-(2,4-dichlorophenyl) -6-Nitro-1,4-dihydroquinoxaline (2ClN-Q) on carbon steel corrosion in 1M HCl solution at different temperatures were investigated using electrochemical measurements and Scanning electron microscopy (SEM) analysis. It is found that the inhibition efficiency increases with 2ClN-Q concentration and decreases with temperature. Polarization data showed that 2ClN-Q actes as mixed-type inhibitor, while EIS results revealed that the 2ClN-Q species adsorbes on the metal surface. This adsorption followed Langmuir adsorption isotherm. SEM studies revealed the formation of a protective film on the carbon steel surface such as indicated by EIS.
