Consequently, interphase fractionation of heavy hydrogen isotopes occurred in stationary water-mineral systems. The coefficients of tritium interphase fractionation range from α = 1.26 for palyhorskite to α = 2.96 for clinoptilolite. For deuterium, this indicator is equal to α = 0.89 for clinoptilolite and to α = 1.10 for saponite. Product Description popup.authors Malkova Yana O. Sevruk Iryna M. popup.nrat_date 2025-01-07 Close
