Laboratory and Field Methods for Determination of Bromate in Drinking Water

Funded under: FP5-GROWTH


A new European directive regarding levels of minerals in drinking water makes dramatic improvements in the technology for detecting bromate ions a necessity.

The legal limit is now 10 micrograms of bromate per liter of water, which is not detectable in many water analysis laboratories. A collaboration of EU scientists have been developing the techniques needed to enforce the directive. They have collected data on the effect of other impurities on measurements, the stability of the bromate ion under varying conditions and the effectiveness of existing measuring equipment. The aim was to produce an automated technique for detecting concentrations of bromate at the microgram per liter level, and to work on an accurate, portable field-based measuring device. They have developed one spectrophotometric batch method and one flow injection method with colormetric detection, using a reaction between bromate and chlorpromazine which gives a coloured product.

Several new techniques which meet the requirements of the European directive have emerged from the research. Bromine has industrial applications in organic synthesis reactions, fire retardants and fumigants. This compound can react with ozone to form carcinogenic bromoacetates, so it is important to know how much of it is loose in the environment. nt.
