I need help on how to investigate the corrosion inhibition performance of vegetable oil in tetraoxosulphate (VI) acid (H2SO4) environment using potentiodynamic polarization method. Does anyone have the idea of the right solvent to use since the acid and vegetable oil will not form solution in each another (immiscible) and oil not soluble in water or has anyone done such test?
Your suggestions and contributions will help me a lot, kindly reach me via this platform or my e-mail ([email protected]).
Thanks in anticipation.
Hi, if there is no specification how to test the inhibitor performance, you can try to mimic the environment in which the inhibitor is used.
If a substance is not soluble often a kind of emulsifier is used. But this is maybe not the way, your inhibitor will work in your specific application. Is the oil applied first to the metal (like in temporary corrosion protection) and then the product is put into the environment?
