STUDY OF SOME MINERAL WATER OF UVS NURSKOY AYMAK OF MONGOLIA

Abstract

The article presents the results of studies on the current state, properties and chemical composition of some mineral waters of the Uvs Aimak, located in the west of Mongolia. The article presents the results of studying the mineral waters in different sums of Uvs aimak in Mongolia, such as Malchin Sagil, Tsagaanhayrhan, Umnugobi, Turgun, Tarialan, Zuungobi, Ulaangom and others. For each sample, 37 standard indicators were obtained using a conventional in hydro-chemical practice traditional chemical methods (weight and volume) and the highly sensitive method of spectrometric study of mineral waters. The results showed that the composition of 11 mineral sources referred to sodium and potassium groups of bicarbonate and the sulphate classes with weak alkaline conditions. According to research history of Uvs province, for the first time, in 1960, chemists O. Namnandorj, E.M Murzaev, and Sh. Tsegmed undertook research on Chandmani spring, Khar тermes spring and Givantin spring, respectively. But the chemists determined only contents of macro elements in their research. There are few research data of studying micro elements, dissolved gas and bioactive elements. The sources had a high content of sulphate ions. As compared with the results obtained in 1960, the mineralization of the most mineral sources tends to increase. The mineral waters studied differ insignificantly between each other in the relations of physical properties and chemical composition. We found that most of the studied waters belong to the first type of calcium group of the hydrocarbonate class, to waters with a weak alkaline medium (pH = 6.94-8.74), with a large mineralization (197.67-1577.25 mg/L) according to the mineral water classification system. The mineralization of these waters has a strong correlation depending on the content of cations Mg2+, Na+ + K+, etc., as well as anions SO42- and HCO3-.Forcitation:Ulziikhishig I., Sukhbaatar I., Battumur T.
