| Abstract: | Three organic
inhibitors namely, 5-mercapto-3-butyl-4-salicylidineimino-1,2,4-triazole
(MBST), 5-mercapto-3-butyl-4-benzylidineimino-1,2,4-triazole (MBBT) and
5-mercapto-3-butyl-4-cinnamylidineimino-1,2,4-triazole (MBCT) were synthesized
in the laboratory and their influence on the inhibition of corrosion of mild
steel (MS) in aqueous solutions containing 1N HCl and 1N H2SO4 was
investigated by weight loss and potentiodynamic polarization techniques. The
inhibition efficiency (IE) of these compounds was found to vary with
concentration, temperature and immersion time. Good inhibition efficiency (IE)
was evidenced in both acid solutions. The adsorption of these compounds on the
steel surface for both acids was found to obey Temkin’s adsorption isotherm.
The potentiodynamic polarization data have shown, that, compounds studied are
mixed type inhibitors in both the acid solutions. |
