Abstract
Liquid phase mass transfer coefficients were determined for streams of bubbles of pure oxygen, 10% carbon dioxide in air, and 10% chlorine in air all rising in water. The results were compared with coefficients predicted by Higbie's equation for unsteady state diffusion into transient films. The observed coefficients for oxygen and carbon dioxide were slightly higher than predicted. The experimental absorption coefficients based on the free chlorine concentrations were in good agreement with the predictions assuming simultaneous irreversible reaction with the transient water film and a pseudo first‐order reaction rate constant of 13.7 sec.−1.
