THE INHIBITION OF STEEL CORROSION IN ACIDIC SOLUTIONS BY A NEW SCHIFF BASE

The inhibition effect of 2,2'- (((thiobis (4,1 phenylene)) bis(azanylylidene)) bis(methanylyidene)) bis(4-methoxyphenol) (BIS-IMIN) on the corrosion behavior of 304-stainless steel (SS) in 0.5 M HCl solution was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polariz...
