通常的电化学研究中,有关电极附近液层参与反应粒子的传质过程多局限于理论分析,其实验研究,即使应用Fick定律分析液相的扩散传质现象,也多限于简单的均态体系.对于复杂多相体系的液相传质问题,更近乎束手无策.鉴于液相传质研究在理论上和实际应用中的重要性,作者等近年采用透射Vop光谱椭圆法对电化学体系中的传质过程进行了实验探索,本文扼要介绍该法的研究概况.
In electrochemical system, the mass transport process in liquid layer adjacent to electrode is studied through theoretical analysis only.The diffusion process can be analyzed theoretically by Fick's law for homogeneous media. Up to now, none of satisfied experimental method has been reported for studying mass transport of a whole process in liquid media yet. This paper described the experimental approach to explore mass transport in electrochemical system by transmission Vop-spectroellipsometry briefly.
