Description

The rate of absorption of carbon dioxide into aqueous sodium carbonate-sodium bicarbonate solutions has been measured at 25°C in a 12.3 cm I. D. agitated vessel with a flat gas-liquid interface. Experiments have been carried out under conditions where gas absorption is accompanied by an irreversible pseudo-first order reaction. The experimental results have been analyzed by chemical absorption theory based on the Lévêque model and show good agreement with theoretical predictions for gas absorption with an irreversible pseudo-first order reaction between dissolved carbon dioxide and hydroxyl ions in carbonate-bicarbonate solution.
