Flow kinetics of nylon open-tubular and beaded immobilized glucose oxidase reactors.
Equations describing the flow kinetics of immobilized glucose oxidase in open nylon tubes and in tubes filled with solid glass spheres were experimentally determined. Reactors of three different tube (dt) and bead (db) diameters were tested using various linear flow rates (vf) and glucose concentrations ([S]). The kinetics of the open-tubular reactors were described by [P] = 1.5.10(-3) [S] L0.86 vf-0.78 dt-0.9 and the kinetics of the beaded-tubular reactors by [P] = 5.10(-3) [S] L0.98 vf-0.75 dt-1.0 (db/dt)2.7, where [P] equals the concentration of H2O2 formed. The aspect ratio, db/dt, is the critical design factor for beaded reactors.
