Development of ion chromatography in Ukraine

The ways of development of ion chromatography in Ukraine from the eighties of the last century to the present time are shown. The achievements of research institutes, in particular, the Dumansky Institute of Colloid Chemistry and Water Chemistry of the National Academy of Sciences of Ukraine, in the development of ion chromatographic methods for the analysis of organic and inorganic anions in various objects, including natural and drinking waters, are highlighted. Scientists of Ukraine (A.T. Pilipenko, O.V. Zuy, A.V. Terletskaya) compared commercially available sorbents for ion chromatography – HIKS-1, ANIEKS-N and KANK ASt for their use in water analysis. The studies were carried out on an ion chromatograph "Tsvet-3006" with a conductometric detector. It has been shown that ANIEKS-N with a borate eluent is the best sorbent for the determination of organic monocarboxylic acid ions, and KANK ASt with a carbonate-hydrocarbonate eluent – for the determination of inorganic anions. Ion chromatography has been used to solve a number of practical problems: for the separation of oxoanions  iodate, chlorate and bromate in waters, to control the results in the development of chemiluminescent methods for the determination of chloride, nitrite and nitrate, to establish the mechanism of destruction of anionic surfactants under the action of vacuum ultraviolet radiation and corona discharge. The method was applied to the analysis of iodine-containing bottled waters for bromide ions due to the absence of the interference from iodides. The accumulated experience has contributed to the adoption in Ukraine of four state standards for water quality, based on the use of the ion chromatographic method. It is shown that the method of ion chromatography at the present stage is widely used in various sectors of the national economy: to determine the traces of anions in steam condensate of power plants, to control the anionic composition of water at nuclear power plants, to correct water treatment processes at waterworks, in particular, when analyzing chlorite ions in tap water obtained with the use of chlorine dioxide as a disinfectant.
Keywords: ion chromatography, sorbents, eluents, organic anions, inorganic anions.
