A Flow Injection, Non-Ion Chromatographic Method for Measuring Low Level Bromate Ion in Ozone Treated Waters

A flow injection, non-ion chromatographic method has been developed using chlorpromazine for the determination of bromate ion in ozone treated waters containing bromide ion. The procedure has been automated over a linear operating range of 1.0 to 30.0 μ/L The precision of the method in reagent water is calculated to be better than 2.5% with an accuracy within ± 1 μ/L The method detection limit (MDL) is 0.8 μ/L. Chemical masks are described to minimize potential interference from nitrite ion and chlorite ion.
