A COMPARATIVE STUDY OF CORROSION INHIBITIVE EFFECTS OF SOME SCHIFF BASES ON METAL IN ACIDIC MEDIUM

Rajeev Mathur, Priya Mathur, Dr. V. K. Swami

Abstract :

Mass loss techniques have been employed to study the corrosion inhibition of some newly synthesized Schiff bases viz. N-(2- Methoxy bezalidine)-2- Amino pyrimidine (SB1), N(3-Methoxy benzalidine)-2- Amino pyrazine(SB2) for copper metal in HC1 solutions. Results of inhibition efficiencies from the mass loss technique show that Schiff bases are good inhibitors in acidic solution. Inhibition efficiency increases with the increase in the concentration of acid as well as those of inhibitors. Maximum inhibition efficiency is shown at highest concentration of Schiff bases at the highest concentration of acid.
