摘　　要：电化学石英晶体微天平(EQCM)即石英晶体微天平(QCM)与电化学检测相结合的测试技术。电化学石英晶体微天平以其简单、快速,可以在纳克级水平上对活性物质在石英晶振片上发生的沉积、吸附或溶解等过程进行动态检测等优势而成为表界面反应研究的有效手段之一。由于EQCM测试技术为原位测试方法,可以实现在线实时监测,利用其高精度和高灵敏度可以进一步对表界面上发生反应的过程及深层次的机理进行分析。本文就EQCM在电化学、生物医学及油田化学等领域以及研究机理及动力学等方面的应用进行了总结阐述,提出了EQCM的研究新方向以及发展中面临的问题。Electrochemical Quartz Crystal Microbalance (EQCM)is a testing technique that combines quartz crystal microbalance (QCM)and electrochemical detection.EQCM is one of effective methods to study the surface reaction due to its simplicity,rapidness,and the ability to dynamically detect the deposition,adsorption, or dissolution of an active material on a quartz crystal at nanogram level.At the same time,because the EQCM testing technology is an in-situ testing method,online real-time monitoring can be realized.With its high precision and high sensitivity,it is possible to further analyze the reaction process and deep-level mechanism at the surface interface.This paper summarizes the application of EQCM in the fields of electrochemical, biomedical and oil field chemistry,as well as research mechanism and dynamics,and puts forward the new research direction of EQCM and the problems in its development.
