Abstract

The kinetics of absorption of oxygen in aqueous solutions of sodium dithionite was studied in a jet apparatus. The reaction was found to be first order with respect to dithionite for dithionite concentration below 0·08 g mole/l. and second order with respect to dithionite concentration above 0·08 g mole/l. The reaction was also studied in a stirred cell and a small laboratory packed column. The reaction was found to be zero order with respect to oxygen for all dithionite concentrations. The effect of sodium hydroxide concentration on the reaction rate constant was also investigated.
