A generalization of kinetic data on sulphite oxidation systems

Kinetic data of the reaction between sulphite ions and dissolved oxygen depend on the purity of sulphite used. Thus it is adequate to determine them for each batch and concentration of sulphite used. Besides the dependence of reaction rate constants on catalyst concentration, it is usually also requ...

Description
Summary:Kinetic data of the reaction between sulphite ions and dissolved oxygen depend on the purity of sulphite used. Thus it is adequate to determine them for each batch and concentration of sulphite used. Besides the dependence of reaction rate constants on catalyst concentration, it is usually also required to know their dependence on pH and on temperature. Both quantities can change to a great extent especially in absorption apparatus in which high sulphite conversion occurs. They profoundly influence the value of the reaction rate constant. To get a complete picture of the influence of these three quantities without repeating extensive kinetic measurements for every kind and concentration of sulphite used, a method for obtaining information on the influence of all three quoted quantities in the range of values of interest for application is presented.
