Absorption rates of pure oxygen gas into sodium dithionite solution with sodium hydroxide were measured at 20 and 30°C in a laminar jet. Absorption rates were also measured under 0.315 to 4.0 atm of oxygen pressure in a continuous stirred tank. From analysis of the data on the basis of chemical absorption theory, the rate equation of chemical reaction for molecular oxygen A was obtained, where the molar ratio of sodium dithionite B to sodium hydroxide is lower than 1/2, as rA=k0, 1.9C0AC1.9Bwhere k0, 1.9=(3.7±0.7)×1010 exp (-1.20×104RT) [(l/g-mole)0.9 sec-1] The absorption for the bubble stirred tank showed that the reaction orders for respective chemical species are reasonable. Furthermore, the homogeneous reaction assay in the continuous stirred tank established that this rate equation of chemical reaction is reasonable.
