The interface temperature rise and relevant enhancement factor have been analyzed for absorption with an instantaneous irreversible reaction and with a first-order irreversible reaction, The modified Danckwerts analysis, called the modified
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
