本文采用国产溶氧电极确定空气-水系统的 K_La.根椐电极特性在亚硫酸钠水溶液中进行脱氧,简化和改进了已有文献的计算式.经三种较低搅拌转速的实测和估算,得到的 K_La 与文献报道的数值相近且τ_E 基本一致.
In this paper, domestic dissolved oxygen electrode was used to determine the K_La of air-water system, and the characteristics of anode and cathode electrode were deoxygenated in the aqueous solution of sodium sulfite to simplify and improve the calculation formula of the existing literatures.By the measurement and estimation of the three lower stirring speed, K_La and reported in the literature similar values and τ_E basically the same.
