Abstract

The mathematical model of diffusion process in polarographic determination of dissolved oxygen has been thoroughly studied with an electric simulator. It is found that the combination of microelectrode and impulse operating technique is a possible way to improve the characteristics of present Clark electrode. The quantitative relations between the electrode size and operating condition are given in this paper in dimensionless form

and the range of the optimum condition has been discussed.
