Figure 9


Fig. 9. Example of mathematical modeling of reaction rate and effectiveness factor for the case with diffusion for various values of k1 and k2 with a fixed diffusion distance (L=104.5) and O2 boundary concentration of 7.85 µmol l–1. The experimentally measured rate of AP recovery of 0.379 mmol l–1 min–1 is indicated by the unbroken line, which shows the range of values of k1 and k2 that satisfy this rate (left panel), and the corresponding effectiveness factor (right panel). Values of k1 and k2 that satisfied the observed rate and maximized the effectiveness factor were then determined using a root-finding method (see text).
