| Abstract | ||
| 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) is investigated using weight loss method. The results show that the presence of about 1.2 % (v/v) of curcuma extract gives about 84% inhibition indicating its effectiveness on mild steel corrosion in simulated refinery wastewater, besides the adsorption process on the mild steal surface obeys the Langmuir adsorption isotherm. | ||
