Abstract
Four n-alkyl amines (6, 8, 10 and 12 carbon atoms) were investigated a s corrosion inhibitors for mild steel in 2 M hydrochloric acid solutio n using gravimetric and polarization techniques. The influences of tem perature (278-308 K) and inhibitor concentration (10(-1)-10(-6) M) wer e studied. Protection efficiency improved when the inhibitor concentra tion and the length of the alkyl chain were increased. The four amines tested were adsorbed on the mild steel surface according to a Frumkin isotherm. Copyright (C) 1996 Elsevier Science Ltd
