摘要：

The electrochemical behavior of copper in deaerated 1.0 M HCl solutions in the absence and presence of Fe(III) and benzotriazole (BTAH) has been studied with rotating disk electrodes. Corrosion potential measurements vs. angular velocity of the disk and anodic polarization data showed that BTAH does not affect the corrosion mechanism of copper in 1.0 M HCl solutions containing ferric ions. The cathodic half reaction is under diffusion control while the anodic half reaction is under mixed control. The presence of Fe(III) ions does not affect the copper anodic dissolution mechanism in 1.0 M HCl medium in either the absence or presence of BTAH.
