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

Abstract

Abstract: Alow-temperature thermostat and a low-temperature electrochemical cell havebeen designed. At different temperature the voltammograms have been recorded by BAS 100B electrochemical analyser.The diffusion coefficients Dof ferrocene at different temperature have been evaluated.The relationship between lgDand 1/Tis 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.

Key words: Electrochemistry, Low temperature, Thermoatat, Voltammetry
