Corrosion Inhibition of Mild Steel by Curcuma Extract in Petroleum Refinery Wastewater

Corrosion Inhibition of Mild Steel by Curcuma Extract in Petroleum Refinery Wastewater

The inhibitor property of curcuma longa L. extract in different concentrations of simulated refinery wastewater (0.05% - 2% wt) and at various temperatures (30, 35 and 40 ˚C) was investigated using weight loss method. The results showed that the presence of about 1.2 % (v/v) of curcuma extract gave...
