摘要
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.
The volumetric oxygen transfer coefficient K_La in air-water system was determined with oxygen electrode of domestic made.Oxygen was removed in Na_2SO_3 solution based on the electrode performance,and the computational method was worked out by simplifying those from the literatures.The K_La value was obtained through the observation and estimation of three kinds of lower mixing speed.The values so obtained are close to and coincide on the whole with those from literatures.
