The effect of benzotriazole (BTA), tolytriazole (TTA), benzo (c) cinnoline (E1), benzo (c) cinnoline 5-oxy (E2), 2,2-dinitro benzidyn (E4) and 2-Aminobenzo (c) cinnoline (E5), were investigated on the corrosion of pure zinc metal in four different aqueous solutions. The corrosion rates of the species were determined by electrochemical current density-potential curves. Primary studies have shown that BTA and TTA have inhibitory effect on copper, and compounds containing nitrogen and sulphur

The results revealed that BTA and TTA act as effective inhibitors on zinc in HCl, NaOH and NaCl solutions. Cinnolines were only effective in NaOH solution.
