Inhibition of the Sulfide Induced Pitting of Copper Nickel Alloy using Benzotriazole

Benzotriazole (BTAH) affects the localized corrosion of Cu10Ni alloy in 3.4% NaCl salt water containing 2 ppm sulfide ions. BTAH concentrations > 5 x 10-4 M imparted corrosion inhibiting efficiency that increased with its concentration. On the other hand, a concentration of 10-4 M BTAH acted as a...
