Analysis of Oxyhalides (SI-52 4E)

 

Please use this column with suppressor type ion chromatography system.

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.

Sample: 50µL

1. F– (2mg/L)  2. ClO2– (1mg/L)  3. BrO3– (1mg/L)  4. Cl– (10mg/L)  5. NO2– (5mg/L)  6. Br– (10mg/L)

7. ClO3– (1mg/L)  8. DCA-, Dichloroacetate (1mg/L)  9. NO3– (30mg/L)  10. PO43- (15mg/L)  11. SO42- (40mg/L)
