【摘要】: The oxyhalides chlorite, chlorate, and bromate are inorganic disinfection by-products (DBPs) of considerable health risk concern worldwide. The occurrence of chlorite and chlorate is associated with the use of chlorine dioxide, as well as hypochlorite solutions used for drinking water disinfection. The occurrence of bromate is associated with the use of ozone for disinfection, wherein naturally occurring bromide is oxidized to bromate. Bromide is a naturally occurring precursor to the formation of bromate.1.1 This multi-test method covers the determination of the oxyhalidesx2014;chlorite, bromate, and chlorate, and bromide, in raw water, finished drinking water and bottled (non-carbonated) water by chemically and electrolytically suppressed ion chromatography. The ranges tested using this method for each analyte were as follows: RangeSections Test Method A: Chemically Suppressed Ion Chromatography

8 to 18
Chlorite
20 to 500 x00B5;g/L

Bromate
5 to 30 x00B5;g/L

Bromide
20 to 200 x00B5;g/L

Chlorate
20 to 500 x00B5;g/L

Test Method B: Electrolytically Suppressed Ion Chromatography

19 to 29
Chlorite
20 to 1000 x00B5;g/L

Bromate
1 to 30 x00B5;g/L

Bromide
20 to 200 x00B5;g/L

Chlorate
20 to 1000 x00B5;g/L
