Abstract

A model for the production of singlet delta oxygen, O₂(¹(Delta) ), following the reaction of gaseous chlorine, Cl₂, with liquid basic hydrogen peroxide, BHP, is described. The model includes diffusion of the Cl₂ gas into the liquid, diffusion of the hydroperoxy anions, HO^-₂, to the surface, reaction of the Cl₂ with the HO^-₂ ions at a finite-rate, heterogeneous deactivation of the O₂(¹(Delta) ) within the liquid, and homogeneous deactivation of the O₂(¹(Delta) ) molecules in the gas. Transport equations are written for the chlorine, oxygen, and HO^-₂ species concentrations in the liquid while ordinary rate equations are written for the chlorine and oxygen species in the gas. The appropriate initial and boundary conditions for these coupled, nonlinear equations are discussed. Several assumptions and approximations, justified because of the existence of several widely disparate temporal and spatial scales associated with the convection, diffusion, and reaction of Cl₂ with BHP, are discussed and applied to simplify these coupled equations.
