Characterisation of micromixing efficiency by the iodide–iodate reaction system. Part II: kinetic study

In a previous paper (Part I), the operating conditions of the iodide–iodate reaction system used to quantify micromixing phenomena in chemical reactors and mixers has been presented. In order to determine the micromixing time through models, the complete kinetics of the reactions must be known. This paper presents the kinetics of the Dushman reaction obtained in operating conditions close to the micromixing test conditions. The results confirm the single fifth-order process widely reported in published work and establish the rate constant as a function of ionic strength ranging between 0 and 2 M.
