Effect of Intensifier Additives on the Performance of Butanolic Extract of Date Palm Leaves against the Corrosion of API 5L X60 Carbon Steel in 15 wt.% HCl Solution

The quest to replace toxic chemicals in the nearest future is revolutionizing corrosion inhibitor research world by turning its attention plant biomaterials. Herein, we report inhibiting potential of butanolic extract date palm leaves (BUT) on API 5L X60 carbon steel 15 wt.% HCl solution. mass loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), linear (LPR), scanning electron microscopy (SEM), energy dispersive X-ray (EDAX), and atomic force (AFM) techniques were employed investigation. We also effect intensifier additives, namely formic acid (FA), potassium iodide (KI), zinc nitrate (Zn(NO3)2) as well temperature performance BUT. BUT exhibits ability but extent inhibition dependent concentration, temperature, intensifiers’ concentration. At 25 °C, 200 mg/L 700 protected surface 50% 88%, respectively. addition 3 mM FA 5 KI upgraded 97% 95%, Zn(NO3)2 performs poorly an for under acidizing conditions. adsorption + synergistic nature whereas that drifts towards antagonistic behavior according calculated synergism parameter. Increase system resulted a slight decline efficiency with above 85% achieved at 60 °C. SEM AFM results corroborate from techniques.
