Determination of deuterium concentration in water |
| abstract |
Water samples having a predetermined concentration of deuterium are equilibrated with a hydrogen containing reagent at such conditions as to allow migration of hydrogen and deuterium ions between the reagent and water. The reagent is then analyzed to determine the isotope ratio of molecules containing deuterium to those containing hydrogen. From the data, a correlation between isotope ratio and the concentration of deuterium in water is established. The sample of water having an unknown concentration of deuterium is then equilibrated under the same conditions with the same reagent. The equilibrated reagent is analyzed to determine mass isotope ratio which is converted to deuterium concentration in water using previously established correlation. Deuterium concentration in water is then used for obtaining geothermal data. |
