ABSTRACT
The inhibiting effect of Leptadenia hastata (Yadiya) leaves extract on the corrosion of mild steel in 1 M HCl and 1 M H2SO4 was studied by weight loss measurement. Different concentrations of Leptadenia hastata leaves extract were prepared ranging from 0 to 1000 ppm for the inhibition of mild steel corrosion at room temperature. The prepared samples of mild steel were exposed to the corrosive media and the corresponding weight loss subsequently obtained was recorded at intervals of 72 hours. The inhibition efficiency increased with increasing inhibitor concentration, while it decreased with increase in time. Likewise, inhibition efficiency (IE) from the findings revealed an increased (with at least 12.48 % in HCl, and 0.78% in H2SO4) with increase in the inhibitor concentration from 0-1000 ppm. The results indicate that the extract could be used as inhibitor.
