초록

변전위법, 순환전압전류법, 대시간전류법 및 대시간전기량법을 이용하여 구리의 산화 용해반응에 미치는 $Cl^-$의 영향을 조사하였다. 아르곤 분위기의 NaCl 수용액에서 Cu의 산화 용해반응은 전반응식 $Cu+2Cl^{-}{\rightleftharpoons}{CuCl_2}^{-}+e^-$ 에 따라 일어나며, Cu 표면에 $Cl^-$가 흡착하는 과정에 잘 맞는 등온식은 Temkin 흡착등온식 임을 알 수 있었다.

We investigated chloride ion effects on anodic dissolution of copper using potentiodynamic method, cyclic voltammtery, chronoamperometry and chronocoulometry. The anodic dissolution reaction of copper in NaCl solution under argon atmosphere is $Cu+2Cl^{-}{\rightleftharpoons}{CuCl_2}^{-}+e^-$ and chloride ion adsorption process in copper surface can be explained by Temkin isotherm.
