Hu S., Hu D., 2015, Kinetics of the Preparation of Chlorine Dioxide by Sodium Chlorite and Hydrochloric Acid at Low Concentration, Chemical Engineering Transactions, 46, 49-54.
The kinetics of the reaction between sodium chlorite and hydrochloric acid is studied at various temperatures and molar concentrations of chlorite and acid at low concentrations. The reaction rate law is established, and macrokinetics formula is obtained. Reaction has been found 1 and 1.39 order with respect to chlorite and hydrochloric acid respectively when preparing chloride dioxide using low concentrations of sodium chlorite and hydrochloric acid. The temperature dependence of the reaction is also investigated and pre-exponential Arrhenius parameter as well as activation energy are determined.
