(a) Photodegradation of PFOA by Fe-BEA35 zeolites with various iron contents; (b) pseudo-first-order kinetics fit. 1 g L–1 zeolite, C0,PFOA = 48 μM, pH0 = 5; (c) UV–vis DR spectra of iron-exchanged BEA35 zeolites with various iron contents in 10 g L–1 Fe-BEA35 suspension (black line). Simulated deconvolution curves for UV–vis DR spectra of the Fe-BEA35 suspension (dashed lines). Error ranges stand for the standard deviations of the results from triplicate assays in (a). Lines serve as guides for the eye in (a) and (b).
