Adsorption And Corrosive Inhibitive Properties Of Some Naturally Occurring Substance (A Case Study Of Extract Of Root And Fruits P Eeks In Alkaline And Acidic Media):- Dick, Osivuemeh H
ABSTRACT
The present study examined the adsorption and
corrosive inhibitive properties of neem root on mild steel in alkaline and
acidic media. The objectives of the study were to extract liquid from
Azadirachta indica (neem) root; inhibit the corrosive mild steel in H2SO4 and
NaOH solutions and examine the effects ofinhibitor and corrodent concentration
on inhibitor efficiency. The neem root was obtained from the neem trees in
Michael Okpara University of Agriculture, Umudike. The stock solution ofthe
extract obtained was used in preparing 0.5N, 1 .ON H2SO4 and NaOH for mass loss
method and 3N, 4N, and 5N H2SO4 and NaOH for thermometric analysis,
respectively. The weight loss experiment was carried out at 30 and 60°C. The
result showed that the corrosion rate was found to increase with increase in
the corrodent concentration and also with increase in temperature. The extract
from the neem root was found to be an inhibitor for mild steel in 0.5 M 112SO4
and NaOH. However, the metal was found to corrode faster in NaOH than in H2SO4
solution. Inhibition efficiency increased with increase in inhibitor
concentration. It was therefore recommended that natural plant extracts such as
neem root extract can be utilized as a corrosion agent against corrosion in
both acidic and alkaline environment.
