ABSTRACT:
The inhibition efficiency of acid extract of leaves of Tectona grandis [TG] on the corrosion of mild steel in 0.5 M H2SO4 was investigated by weight loss measurements and polarisation studies. The results obtained show that the extract could serve as an effective inhibitor for the corrosion of mild steel in H2SO4 media. Inhibition was found to increase with increasing concentration of the plant extract. Polarization curves revealed that this inhibitor acts as a mixed type inhibitor. The inhibition efficiency of up to 97.46% at 2.5 %( v/v) concentration of the extract was obtained.
