摘要:

利用动电位扫描技术,研究了铜阳极在硫酸介质中的电化学行为,考察了不同电解液浓度、不同保持时间、不同保持电位以及电解液中分子氧及Cu2+的存在对铜阳极循环伏安曲线的影响.结果发现:电解液中分子氧及Cu2+的存在、较长的保持时间、较正的保持电位均能使峰电流增大,有利于金属的钝化;不同浓度H2SO4介质中形成的钝化膜都有两层组成,但其组成不同,并对铜的钝化机理作了进一步的推断.

Abstract:

The electrochemical behavior of copper anode in sulfuric acid medium was studied by potentiodynamic scanning technology, and the effects of different electrolyte concentrations, different holding times, different holding potentials, and the presence of molecular oxygen and Cu2+ in the electrolyte on the cyclic voltammetry curve of copper anode were investigated. The results show that the presence of molecular oxygen and Cu2+ in the electrolyte, a longer holding time and a more positive holding potential can increase the peak current, which is conducive to the passivation of the metal. The passivation film formed in different concentrations of H2SO4 media has two layers, but its composition is different, and the passivation mechanism of copper is further inferred.
