Monitoring of Drinking Waters for the Content of Bromide, Iodide, Bromate and Iodate Ions

Аннотация

The monitoring of potable artesian waters of the city of Kyiv for bromide, bromate, iodide, and iodate ions as well as of drinking bottled water for bromides and bromates has been carried out. Bromate, iodide and iodate ions were monitored by the established methods and bromide ions—by the developed method. The stability of the chemical composition of artesian waters of the same horizon is noted. On the other hand, the concentration of bromides and iodides varied 3–4 times in pump-rooms feeding on a mixture of waters from aquifers. For waters containing high concentrations of bromides and iodides, ozonation is counter indicated due to hazard of the formation of carcinogenic bromates and iodates. A conclusion was made that it is more expedient to use carbon dioxide treatment for canning and disinfection of such waters.
