ã€Abstractã€‘ The pseudo-first order reaction rate constants of the reaction between CO2 and Na2CO2-NaHCO3 buffer solutions catalysed by AsO2- and ClO- respectively at 25â„ƒ Â±0 .2â„ƒ are investigated in liquid laminar jet, wetted-wall column and the stirred cell. The characteristics of the apparatus, the methods of the data treatment and the results obtained are discussed and analyzed. These results are further compared with those in the literature.æ›´å¤š è¿˜åŽŸ
