• The overall coefficient of mass transfer based on liquid concentration, KL, for absorption of bubbles into a liquid flowing down countercurrently has been related to the decrease in volume, area and buoyant force of bubbles in order to establish a theoretical equation for KL. The decrease of KL with increase height of column has been found to be fundamentally influenced by the decrease of V/A and the inclination -(d/dθ) ln(FZ) of the bubbles. This work also shows the state of counterdiffusion between carbon dioxide in bubbles and air dissolved in downflowing water, and that air in bubbles can be thought to give the gas-side resistance in the double film theory. It is one of the causes of the decrease of KL when the air content of bubbles increases greatly in cases where the residence time of bubbles in water is comparatively long.
