The possibility of using mineral adsorbents for cleaning the moderator of heavy water reactors from tritium is determined. Three dynamic systems have been created using montmorilonite, sepiolite and palygorskite clays, and zeolite (systems M-Z, S-Z and P-Z) as composite membranes. At the first stage, deuterium-tritium water (DTO) was filtered through mineral membranes, and at the second stage, these membranes were washed with protium water (Н 2 О). In the process of such two-stage filtration, the effect of separation of tritium and deuterium in the filtrate was first established. At the first stage of the experiment, the content of deuterium and tritium in the DTO filtrate in the system with the M-Z membrane was equally re- duced and at the end of the filtration was slightly more than 50% of the initial concentrations. The separation coefficient of heavy hydrogen isotopes in this system did not exceed K T = 0.99. When DTO was filtered through the C-Z membrane, the fraction of tritium in the filtrate at the end of filtra- tion decreased by 10% relative to the initial concentration, which is less than the fraction of deuterium, and the hydrogen isotope separation coefficient was K T = 1.15. In the P-C system, the residual fraction of deuterium in the DTO filtrate was 3% higher than the residual fraction of tritium and the hydrogen isotope separation coefficient was determined at the level of K T = 0.96. A different process is observed when filtering protium water (Н 2 О) through clay-zeolite adsorbents after their interaction with the DTO solution. In all the studied mineral adsorbents, the manifestations of frac- tionation of heavy hydrogen isotopes with coefficients KD = 13.2, 3.2 and 3.6 were established respectively for montmorillonite-zeolite, sepiolite-zeolite and palygorskite-zeolite composites with a predominant deuterium content in the filtrate, which indicates the possibility of using clay-zeolite mineral adsorbents for the purification of heavy water from tritium.
确定了用矿物吸附剂清除重水反应器中氚的慢化剂的可能性。用蒙脱土、海泡石、坡面石粘土和沸石(M-Z、S-Z和P-Z体系)作为复合膜，建立了三种动态体系。在第一阶段，氘氚水(DTO)通过矿物膜过滤，在第二阶段，这些膜用protium水(Н 2 О)洗涤。在这种两级过滤过程中，首次建立了滤液中氚和氘的分离效果。在实验的第一阶段，M-Z膜体系的DTO滤液中氘和氚的含量都得到了同样的还原，在过滤结束时，氘和氚的含量略高于初始浓度的50%。该体系中重氢同位素的分离系数不超过K T = 0.99。DTO经C-Z膜过滤后，滤出液中氚的含量相对于初始浓度下降10%，小于氘的含量，氢同位素分离系数K T = 1.15。在P-C体系中，DTO滤液中氘的残余分数比氚的残余分数高3%，在K T = 0.96的水平上测定了氢同位素分离系数。当与DTO溶液相互作用后，通过粘土-沸石吸附剂过滤protium water (Н 2 О)时，观察到不同的过程。在所研究的矿物吸附剂中，滤出液中以氘含量为主的蒙脱石-沸石、海泡石-沸石和斜长石-沸石复合材料的重氢同位素分别存在系数为13.2、3.2和3.6的断裂现象，表明利用粘土-沸石矿物吸附剂净化重水中的氚是可行的。

A modern conceptual approach to a study of the ecological and hydrogeological transformation of the qualitative composition of drinking groundwater of the buchak-kaniv aquifer in the central part of Dnipro-Donetsk artesian basin in the current natural-technogenic conditions has been proposed in the article. A rational unification of the indicators that characterize geological, ecological-hydrogeological and neotectonic conditions of the territory has been done. According to these conditions – natural and technogenic factors of the water quality deterioration of the target aquifer have been identified and investigated at the present stage. The spatio-temporal patterns of changes in the chemical composition of the studied waters during the period of active complex technogenic influence on the geological environment of the region (1960-2015) have been revealed. The main pollu-tant elements of these waters have been established, with their distribution at depth and surface by genesis. The elements-indicators of qualitative composition transformation of the groundwater have been determined. The authors have traced the dynamics exhibiting an increase in its content during long-term exploitation at about 20 powerful urban water intakes within the work area. According to this approach, measures for the stabiliza-tion of the waters’ chemical composition at the buchak-kaniv water intakes of the research area have been developed. The authors justified a me-thodical approach to the prediction of groundwater ecological condition changes under the influence of the established ecological and hydrogeological factors. The measures of eco-friendly groundwater management at strategically important water intakes within the region have been proposed. Recommendations have been given for both existing and prospective water intakes.
