Transition from Bubbling to Quiescent Desorption of Dissolved Gases

Experiments have been conducted using a simple stirred cell apparatus over the temperature range 22 to 88 °C to elucidate the effects of dissolved gas supersaturation and solvent vapor pressure on the inception of bubbling in desorption from aqueous solution. The transition from bubbling to diffusive desorption is found to occur when the ratio of dissolved gas partial pressure to total system pressure Is unity. It is independent of the solvent vapor pressure
