CO, has been absorbed in a packed column into carbonate-bicarbonate buffer solutions containing arsenite as a catalyst. In these solutions COz undergoes a pseudo-first-order reaction. The results confirm that rates of absorption can be predicted on the basis of the Danckwerts surfacerenewal model. V

✦ Synopsis
Abstmet-In
Part 1 transient rates of absorption of COa into NaOH, NaKOs/NaHCOa and NaaS solutions were measured. These results are here compared with the rates of absorption of COa into similar solutions in a column packed with 4 in. Raschig rings. It is found that the Higbie and Danckwerts surface-renewal models enable these rates to be predicted to within about 10 per cent. The Delta model (al1 surface has same age) is less accurate.
