Description

 Objects of research – natural, drinking water photometric, chemiluminescent, chromatographic methods and biotesting to assess their quality. The purpose of this work is to develop new and improve existing methods for determining the microquantities of toxic components in water, as well as to determine the threshold concentrations of bromide ions that lead to exceeding the maximum allowable concentration (MPC) for bromate ions in water ozonation. Research methods - spectrophotometric, atomic absorption with flame and electrothermal excitation, mass spectrometric with inductively coupled plasma, etc. Main results: a study of the ozonation process of distilled water and tap water of Kyiv with various additives of bromide ions to determine the threshold concentrations of the latter, which lead to exceeding the maximum allowable concentration (MPC) for bromate ions. It is shown that the concentration of Br - ions in water correlates linearly with the concentrations of BrO3- formed during ozonation. This effect is especially important to consider when ozonation of waters with increasing content of bromide ions. The formation of bromate ions is affected by doses of ozone, which is used for effective disinfection of water. At an ozone dose of 1 mg/L, the maximum permissible concentration of bromates may be exceeded for distilled water at a bromide ion content of 40 μg/L, and for tap water at a concentration of Br-> 40 μg/L. At a dose of ozone 0.5 mg/L, the threshold concentration of bromide ions increases and is 60-70 μg/L. Field of application: Ecology, ecological chemistry, ecological safety.
