New inorganic inhibitors derived from cefotaxime to enhance corrosion resistance of mild steel in 3% NaCl.

To overcome the threat of corrosion and its cost, a new Schiff base was prepared and utilized to synthesize inorganic inhibitors to enhance corrosion resistance and reduce current density. The Schiff base was obtained from the interaction of cefotaxime with acetylacetone, while H NMR and IR spectra were used to confirm the preparation. Moreover, Fe, Co, Ni and Cu metal salts were reacted with the Schiff base to give the corresponding complexes.
