Abstract :
Corrosion, which has become a menace to
humans and the society is a subject of concern especially
in the food and pharmaceutical industries. Research in
mitigating corrosion has generated lots of interests
especially in the development of organic inhibitors such
as potato peels, siam weeds, harmal leaves, with
promising results. This work investigated the potentials
of the leaves of Editan (Lasienthera Africanum) extract
for use in formulating inhibitor in corrosion prevention
of Aluminum alloys. The leave was subjected to
phytochemical screening, Characterization was done
using Scanning Electron Microscopy (SEM) and Fourier
Transform Infrared Spectroscopy (FTIR) for the
protective layer and the extracts respectively. Corrosion
test using gravimetric measurement on Al-Si-Mg alloy
coupon in 3.5% NaCl solution was investigated. The
result obtained showed that Lasienthera Africanum
contains phytochemical properties of terpenoids,
saponin, alkaloids, glycosides, tannins. The inhibitor
efficiency was found to improve with increase in
inhibitor concentration. Inhibition efficiency for Editan
was obtained to be 100% at high concentration of extract
(5v/v%), obtained at a temperature of 303 K The results
have confirmed that the leave extract of Editan is a good
inhibitor against corrosion inaluminum alloys.
