Model compound degradation from water in a reactive nanostructured stacked membrane system. (A) Schematic of stacked membrane system for degradation of TCP using glucose and oxygen. Top membrane contains GOx electrostatically immobilized in LbL assembly; bottom membrane contains Fe2+ immobilized in a PVDF-PAA membrane. (B) TCP conversion at steady-state and Cl- formation as a function of time. Squares: 0.14 mmol/L TCP in feed; circles: 0.07 mmol/L TCP in feed. Maximum mol Cl- formed/mol TCP reacted = 3. Steady-state concentration of H2O2 from the first membrane is 0.1 mmol/L (circles) and 0.13 mmol/L (squares), Fe loading = 0.09 mmol, pH 5.5, residence time in the top membrane = 2.7 s, residence time in the bottom membrane = 2 s.
