TCE and H2O2 decay in the iron oxide/PAA/PVDF membrane system (solid line). Dash lines The pseudo-first-order model of H2O2 decomposition [Eq. (4)]. [Total iron loading as iron oxide] = 0.88 g/L, [TCE]0 = 0.270 mM, [H2O2]0 = 41.4 mM, total volume V = 20 mL. pH 7 at t = 0 and pH 6.8 at t = 48 h. Filled triangle Iron oxide/PAA/PVDF, filled diamond control (PAA/PVDF), filled square control (H2O2 decay in the absence of TCE). A small amount of TCE was extracted by PAA–PVDF membranes during the reaction (about 0.04 mM after 48 h). The data used in this figure has been modified to eliminate the extraction effect
