Аннотация
Corrosion inhibition effects of water-soluble peripheral substituted cobalt, copper and zinc metallophthalocyanines (CoPc (1), CuPc (2) and ZnPc (3)) on the copper metal in 0.1 N HCl were investigated by using gravimetric, electrochemical, SEM-EDS analysis and quantum chemical calculations. On the electrochemical investigations and gravimetric analysis the highest inhibitor efficiency was obtained with CoPc (1) at 1 × 10–2 mol/L concentration. SEM-EDS results indicated parallel results and oxygen atom content increased in the order of ZnPc (3), CuPc (2) and CoPc (1). According to the quantum chemical calculations, following corrosion inhibition efficiency ranking was obtained: CoPc (1) > CuPc (2) > ZnPc (3).
