Corrosion Inhibition of Aluminum by Using Synthesized Dipyridinium Salts
 
Document Language : English 
Abstract : ome synthesized bipyridinium rings-containing compounds have been used as inhibitors of corrosion of aluminum in 1 M HCl at 45 degrees C. Three dipyridinium compounds, DMdPyI, HMdPyBr and BMPyEI, and mono-pridinium ring compound, TMPyI, were studied. Corrosion potential-time, cathodic-anodic polarization and impedance electrochemical measurements, and quantum calculations were applied. The study indicated that these compounds work as anodic inhibitors for Al, except higher concentrations of HMdPyBr and BMPyEI has additionally some cathodic inhibitive action. The inhibition efficiency of these compounds increased with increasing the inhibitor concentration reaching a plateau at 1x10-4M and the highest inhibition was observed by the compound BMPyEI. The inhibitors follow Langmuir adsorption isotherm, and the adsorption is endothermic and increase with temperature. The inhibitor compounds are adsorbed mainly physically and spontaneously on the aluminum surface.
