Bromate determination - how to get a
good result
Bromate in drinking water is a by-product of water purification by ozone, and at low ppb ranges it is close to the detection limit of ion chromatography: ask Metrohm how to detect it!
Bromate in drinking water is a by-product of water purification by ozone This anion is suspected to be harmful and therefore has to be monitored in water quality control
The concentrations usually encountered are in the low ppb range and below, that is close to the detection limit of ion chromatography with suppressed conductivity detection.
As an alternative ion chromatography with post column reaction and optical detection may be used.
The two known methods are: post column reaction with o-dianisidine (as described in EPA 317.0); and post column reaction with iodide (as described in EPA 326.0).
For each of these methods, including conductivity detection, a new application note is available from Metrohm UK. Request a free brochure from Metrohm UK ...
