This paper studies the kinetics of the reaction betweenNaClO3, FeSO4, and NaHSO3, which can potentially be usedas an alternative to the conventional lime-limestoneprocess for flue gas desulfurization. The key for theestablishment of a kinetic model of the reaction is to finda way to determine concentrations of reactants orproducts during the reaction. The generation rate of Cl-during the reaction was monitored using a Dionex Series4000i ion chromatograph. Based on the changes of Cl-concentrations at the designed initial reaction conditions,reaction orders for each reactant were derived. Thereaction orders were determined to be 1.1 for NaClO3, 1.1for FeSO4, and 1.4 for NaHSO3. The global rate coefficientsof the reaction at temperatures ranging from 40 to 80 
C weredetermined. Furthermore, the preexponential factor andthe activation energy in the empirical Arrhenius form of thereaction were derived from the relationship betweentemperature and its corresponding observed global ratecoefficient.
