Описан ионо – хроматографический метод определения анионного состава природных вод. Была использована автоматизированная система Metrohm 850 IC Professional, оснащенная детектором проводимости после химического и углекислотного подавления. Основные аналитические характеристики были оценены для каждого из исследуемых аналитов. Достоверность метода была оценена путем анализа сертифицированного эталонного материала для мягкой питьевой воды. Испытание на восстановление проводилось на образцах питьевой воды с шипами. Метод применен для анализа питьевой воды до и после хлорирования, а также высокогорных озер.Выбранные методы были успешно применены для анализа проб воды из высокогорных озер, а также питьевой воды до и после хлорирования. Результаты, полученные в этом исследовании, показывают, что нет никаких признаков загрязнения элементами или анионами в воде озера. Не обнаружено никаких отклонений от юридически приемлемых значений для приоритетных веществ, которые могли бы представлять опасность для водной среды.

An ion chromatographic method for determination of anion composition of natural waters was described. An automated 850 IC Professional, Metrohm system equipped with conductivity detector after chemical and carbon dioxide suppression was used. The main analytical characteristics were estimated for each of studied analytes. The trueness of the method was estimated by analysis of certified reference material for soft drinking water. Recovery test was performed on spiked drinking water samples. The method was applied for analysis of drinking water before and after chlorination, as well as high mountain lakes.The selected methods were successfully applied for the analysis of water samples from high mountain lakes, as well as drinking water before and after chlorination. The results obtained in this study show that there is no indication of contamination with elements or anions in the lake water. There were no deviations found from the legally acceptable values for priority substances, which could present a risk to the aquatic environment.
