Kinetic Studies Of Selected Corrosion Inhibitors Of Aluminium And Mild Steel In Acid Medium

Abstract

The corrosion inhibition of aluminium and mild steel in H2SO4 in the presence of Bromothymol blue, BTB, Dimethyl yellow, DMY, Methyl orange, MO, Titanium (IV) oxide, TO and Cassia Siamea Lam, CSL leaves extract at 303 – 313K was studied using “Absorbance difference” technique. The results showed that inhibition efficiency (%IE) increased with increase in inhibitor concentration (except for BTB, where beyond a “critical” concentration of 0.0007M, it reversed its function and became an accelerator) and decreased with increase in temperature within the range 303 – 313K studied in the absence and presence of inhibitors and halides. The efficiencies increased in the order:

DMY [65.03% (49.72%)] < BTB [67.82% (56.37%)] < CSL [68.79% (58.75%)]

C=C< etc functional groups) which were found to contribute greatly to the inhibitory properties of CSL on aluminium and mild steel.
