ABSTRACT
This chapter examines in detail the kinetics of direct ozone reactions in water, and considers the different kinetic regimes that ozone reactions present. The main objective of ozonation kinetics focuses on the determination of parameters such as rate constants of reactions and mass-transfer coefficients. First, ways to estimate the ozone properties and solubility or equilibrium constant (Henry’s law) are presented since this information is fundamental to any discussion of ozonation kinetics. As already indicated in Chapter 3, the direct reaction between ozone and a given compound B that will be discussed here corresponds to the stoichiometric Equation (3.5), that is, an irreversible second-order reaction (first-order with respect to ozone and B) with z moles of B consumed per mole of ozone consumed. However, with respect to kinetic regimes, the ozone decomposition reaction as first-order kinetics is also discussed.
