The Study of Electrochemistry at Low Temperature(Ⅰ)──Instrumentation and Its Features

设计了一套可用于低温电化学研究的实验测量装置，经测试其性能优良．

A low-temperature thermostat and a low-temperature electrochemical cell havebeen designed. At different temperature the voltammograms have been recorded by BAS100B electrochemical analyser.The diffusion coefficients D of ferrocene at different temperature have been evaluated.The relationship between lgD and 1/T is a straight line.The dif-fusion activation energy E_d of ferrocene is determined as 8.8 kJ/mol. The experimental results show that the system described in this paper is very effective for electrochemical experiments.
