Abstract

The mass loss method was used to analyze the corrosion inhibition of Aluminum in an acid mixture (HCl+ H2SO4) by novel nitrogen-containing ligands (Schiff’s bases), namely, N(vanillidine)-4-methyl-1-phenylimine (SB1), N(vanillidine)-4-methoxy-1-phenylimine (SB2), and N(anisidine)-1-napthylimine(SB3 ).The inhibition efficacy values extracted from the two methods are in good agreement and based on the concentration from the mass loss data. The maximum inhibition efficacy was 91.97% for Aluminum in a mixture of acids (HCl+H2SO4). The outcome show that the inhibition efficacy increases with increasing concentration of the inhibitor.
