Effect of flow rate (i.e. residence time) on the conversion of glucose and the rate of formation of H2O2 for a 15 mM glucose solution fed in a LBL assembled nylon membrane. Model values are calculated considering both plug-flow reactor (PFR) and continuously stirred tank reactor (CSTR) models. Conditions: amount of GOX immobilized, 1.5 mg; volume of LBL membrane reactor, 0.122 cm3; pH 5.5; temperature, 25 °C; permeate flux, (75–265) × 10−4 cm3/(cm2 s); and residence time, 0.35–1.24 s.
