Study of healing springs by determining the pH, total mineralization and free carbon dioxide (CO<sub>2</sub>) of the spring waters in Jizzakh in Uzbekistan
Аннотация
More than 600 samples were collected from 240 springs occupied in different parts of Jizzakh and analyzed for physical (pH), chemical (general mineralization, dissolved free carbon dioxide (CO 2 )). Minimum pH indicator of the springs of Forish district was 6.3 and the maximum result was 7.8. The minimum index of springs located in Bakhmal district is 2.40 and the maximum index is 7.4. In Zomin district, the minimum pH level was 2.9 and the maximum pH level was 7.9, and the level of the spring in Gallaaral district was 7.3. The total level of mineralization of water samples of 9 springs out of 240 and the amount of free dissolved carbon dioxide (CO 2 ) of 26 springs meet the requirements of the Republic of Uzbekistan for healing mineral water, that is, the total mineralization was 1 g/l and more. The amount of free CO 2 is 0.5 g/l and more in spring water. The highest mineralization is 2.1 g/l and belongs to Sho`rbulok spring in Zomin district of Jizzakh region. Springs rich in free CO 2 dissolved in water are located in Bakhmal district of Jizzakh region, the highest indicator belongs to Kizilsuv spring, it was 5.7 g/l.
