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.","PeriodicalId":52701,"journal":{"name":"Geokhimiia tekhnogenezu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47016335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":52701,"journal":{"name":"Geokhimiia tekhnogenezu","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43216071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
