摘要：

The effect of Azadirachta indica leaf (AIL) extract on the corrosion of copper in 1M HNO3 was investigated by weight loss technique. The result showed that the corrosion rate decreased in the presence of plant extract and inhibition efficiency increased with increasing the concentration of extract. The decreased corrosion rate was due to adsorption of plant extract which was discussed on the basis of Langmuir adsorption isotherm.
