a b s t r a c tFe-Al layered double hydroxides (Fe-Al LDH, the molar ratio of Fe(II) to Fe(III) was about 1:10) was successfully supported and highly dispersed on mesoporous Al 2 O 3 based on the X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analysis. Fe-Al LDH/Al 2 O 3 was more efficient in inhibiting BrO 3 À formation and removing organic pollutant taking ozonation alone as control. Further investigation indicated that BrO 3 À reduction by surface Fe(II) was responsible to the complete inhibition of BrO 3 À formation.
