Separation of heavy isotopes deuterium (D) and tritium (T) and oxygen (18О) in water treatment
An important indicator of the quality of water is its isotopic composition. Ordinary water at 99,7% u consists of light water molecules which are formed by natural hydrogen 1Н and oxygen 16О atoms. The remaining 0,3 MOL% are t. izotopologamiisotopic species of water molecules. As a izotopologov in any natural water contains tyazhelokislorodnaya ((H2 17O и H2 18O), heavy (D2 16O) and tritievaya (sverhtyazhelaya), water (Т2 16O), the latter two of which are toxic. The number of natural izotopologov water where atoms Н, D, T, 16O, 17O and 18O are in various combinations, is 18, in which 9 combinations are non-radioactive and radioactive heavy water 9 involving tritium. Heavy variety of water due to its physico-chemical properties and the negative effects on the body are very different from the usual water. Therefore, it is necessary to isotope fractionation of water, empty the water from the heavy isotopes. Now work to improve water quality isotope are maintained in all countries of the world, including Russia. However, existing treatment plant and water treatment and water treatment technologies often fail to meet established objectives for water purification. Therefore, in our country in recent years has developed various advanced methods and technology of isotope fractionation and purification of drinking water from heavy isotopes D, Т и 18O, detailed in this article.
