Inhibition of Mild Copper Metal Corrosion in HNO3 Medium by Acid Extract ofAzadirachta IndicaSeed

Abstract

Efficiency of acid extract of dryazadirachta indicaseed as corrosion inhibitor for mild copper metal in various concentration of (1 N,2 N and 3N) HNO3medium was investigated in the present study. Experimental methods include weight loss, determination of corrosion rate, inhibition efficiency and phytochemical analysis was studied. The results indicateazadirachta indicaseed to be a good corrosion inhibitor of a mixed type and having efficiency as high as 95% at 1% inhibitor concentration in different time duration.
