Recently ozonation has been applied for the disinfection of drinking water. Ozonation transforms a part of bromide (Br–) to bromate (BrO3–), which is a potential carcinogen. Therefore, it is important to measure bromate in drinking water. IC SI-52 4E can analyze common inorganic anions and oxyhalides simultaneously with high resolution. Dichloroacetate (DCA–) as a surrogate substance is also well separated. Water dip and carbonate system peaks do not overlap with other peaks.
