Isotope Purification of Drinking Water from Heavy Isotopes – Deuterium (2H), Tritium (3H) and Oxygen (18O)

Oleg Mosin, Ignat Ignatov


This paper deals with the theoretical, scientific and practical issues of isotopic purification of drinking water from heavy isotopes – D, T, and 18O. The authors conducted the research into the deuterium isotope effects in different cells of various biological objects of microbial, plant and animal origin as a result the conclusion was made about the complex multivariate deuterium impact on the body and the need for consumption the drinking water with a reduced content of deuterium. The effects of deuterium on organism possess a complex multi-factorial character and connected to cytological, morphological and physiological changes. The maximum kinetic isotopic effect observed at ordinary temperatures in chemical reactions leading to rupture of bonds involving hydrogen and deuterium atoms lies in the range kH/kD = 5–8 for C–H versus C–2H, N–2H versus N–2H, and O–2H versus O–2H-bonds. Deuterium depleted water (DDW) with decreased deuterium content (60–100 ppm) has beneficial effects on organism. The design of devices is given that allow purify water from deuterium with the decreased on 50–70% of deuterium.

Key words: deuterium, tritium, 18O, heavy water, deuterium depleted water, isotopic purification
