(a) Photodegradation of PFOA by transition metal ion-exchanged BEA35 zeolites; (b) photodegradation of PFOA using iron-exchanged FAU zeolite and iron-exchanged BEA zeolites with various SiO2/Al2O3 ratios. 1 g L–1 zeolites, C0,PFOA = 48 μM, pH0 = 5. Error ranges stand for the standard deviations of the results from triplicate assays. Lines serve as guides for the eye.
