INTERACTION BETWEEN HTO AND CLAY MINERALS
Abstract
These are precisely clay minerals allow the most effective decreasing tritium concentration in the geoinfiltration flow at the expense of hydrogen-isotopes exchange between water and mineral phases during tritium water migration through sedimentary strata. The intensity and velocity of this process depend on the accessibility of reaction surfaces of mineral particles for HTO molecules which in its turn depends on the structural and chemical-structural properties of clay minerals. The exchange velocity on the phases boundary and tritium diffusiveness in the different parts of water-mineral system (interstitial species, interlayer or zeolitic water and crystal structure of clay minerals) also affect on the process of tritium redistribution between different phases.
