| Abstract: | Carbon dioxide was absorbed in potassium carbonate-bicarbonate buffer solutions. Some of these solutions contained arsenious ion as catalyst. The experiments were performed in a wetted wall absorber, in conditions of stagnant gas phase and at constant temperature, with the aim of elucidating the influence of the carboante ion concentration on the catalytic process. A kinetic equation was obtained, that was critically compared with the experimental data published previously by various investigators. |
