电化学阻抗技术是研究电化学的有力工具,在锌电积中有着诸多研究。本文综述了电化学阻抗技术在锌电积传统阳极、传统阳极改性、非铅基阳极以及阴极中的应用。从电化学阻抗谱中可以获得诸如双层电容、极化电阻、电荷传递电阻等参数来研究电极反应阳极、阴极等反应物的催化活性和耐蚀性,通过这些参数的变化了解锌电积中析氧动力学过程、电极表面形貌变化等。
The electrochemical impedance spectroscopy is a crucial tool in electrochemistry investigations. It is widely used in researches of zinc electrowinning. This paper reviews the application of the electrochemical impedance spectroscopy in the researches of zinc electrowinning Traditional anode, Traditional anode modification, Non-lead anode and zinc electrowinning cathode. From elec-trochemical impedance spectroscopy, we can obtain parameters such as double layer capacitance, polarization resistance, charge transfer resistance to study the catalytic activity and corrosion re-sistance of electrode reaction which include anode, cathode and other reactants. Through the changes of these parameters, we can understand the oxygen evolution kinetics, the change of sur-face morphology of zinc electrowinning.
