Notes:
Liquid phase coefficients were measured for the absorption of oxygen from air to the free interface in stirred vessels. Coefficients for absorption into soft water were independent of the instantaneous dissolved oxygen concentration. Coefficients for absorption into soft water containing a surface active agent were strongly dependent on the instantaneous dissolved oxygen level. The degree of nonlinearity of the coefficients was a function of the rate of agitation of the liquid. The coefficients were independent of the amount of surface active agent added above a very low level. Absorption coefficients for bubble aeration in the same vessels were independent of dissolved oxygen concentration even when the surface active agent was present.
