Abstract: The effect of diethanolamine on the corrosion inhibition of mild steel in cassava fluid was investigated by weight loss measurements. The investigation was conducted at temperatures of 298K and 333K at concentration of 0.5M, 1.0M, 1.5M and 2.0M concentrations of diethanolamine in cassava fluid. The results showed that weight loss recorded decreased with concentration and temperature. Weight loss decrease from 0.0503mm, blank solution to 0.0101mm in 2.0M concentration at 298K and a decrease in corrosion rate of 0.0789mm/yr to 0.0411mm/yr under the same conditions on the 3rd day. Weight loss also decreased from 0.0243mm blank solution to 0.0002mm in 2.0M concentration and corrosion rate also decreased from 0.0380mm/yr to 0.0003mm/yr under the same concentration at 333K, on the 3rd day. Further decrease was also recorded as the day progresses to the 9th day. The highest efficiencies recorded were 98.01% at 0.5M concentration at 298K and 9918% at 2.0M concentration at 333K. The recorded values showed that diethanolamine is an efficient corrosion inhibitor of mild steel in cassava fluid.
