✦ Synopsis

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 carbonate ion concentration on the catalytic process. A kinetic equation was obtained, that was critically compared with the experimental data published previously by various investigators. INTRODUCI-ION The absorption of carbon dioxide in carbonate buffer solutions containing arsenite ion as catalyst is a wellknown process, which, besides its industrial importance, is used among others for the determination of mass-transfer parameters in gas-liquid reactors (Alper
