摘要：
Impact of corrosion inhibitors on environment has received increased attention in recent years. The new generation of environmental regulations requires the replacement of toxic chemicals with so-called "Green chemicals". In the present study neem oil, castor oil and punga oil were used for corrosion inhibition evaluation in petroleum product (diesel) along with 2% water containing 120ppm chloride. Weight loss and polarization studies were employed to find out the corrosion inhibition efficiency (IE). Weight loss study revealed that castor oil gave higher efficiency (89%) when compared to other neem oil and punga oil. The mechanism of corrosion inhibition was investigated by using surface techniques viz., Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM).
