ABSTRACTThe paper presents the results of more than a year running pilot setup for separation hydrogen isotopes using catalytic isotopic exchange between and liquid water. The is 5 m high, has inner diameter 28 mm, equipped with upper lower reflux devices. experimental values HETP vary from 15 cm at T=333 K to 38 T=293 K. capable upgrading diluted heavy water 85–90% deuterium content up [D2O] ≥ 99.95 at.%, yielding daily 4 kg product. We also report on progress in constructing similar...
Abstract The equilibrium distribution of 3 H between hydrogen gas and the intermetallic storage material Ti 0.4 Mn 0.6 n , being in with light hydrogen, was determined by tracer experiments α‐phase region temperature range from 23°C. to –60°C. separation factors follow relationship values show up an enrichment tritium solid solution, whereas PdH ‐system opposite observations are made. It is shown that isotope at higher contents not only energy differences vibrational states. but may also be...
Using the radiation–chemical simulation method of free radical reactions with 2,2-diphenyl-1-picrylhydrazyl, we were able to show high antiradical activity water–ethanol extracts from Murraya paniculata. This will allow for creation new bioactive antioxidants based on them. The formation silver nanoparticles (Ag-NP) was determined using silver-ion reduction process by M. paniculata extracts. A band electronic plasmon resonance identified in optical absorption spectra hydrosols Ag-NP dried...
Experimental equipment for studying the sorption properties of iodine sorbents using radioactive methyliodide has been developed. The capacity index α is proposed as a criterion parameter assessing quality impregnated activated charcoals. It was found that this does not depend on dynamic conditions during sorbent test. shown values allow to recommend industrial gas cleaning processes.
Mineral and synthetic oils used as lubricants or operating fluids in pumps are mixtures of branched cyclic saturated hydrocarbons. They chemically inert but their slow partial oxidation is possible even at room temperature. Specific activity pump contacted with gaseous tritium for a long time may exceed 1013 Bq/kg.Studies waste show that more than 90% the radionuclide bound products. This selectivity owned to predominant formation quasifree tritons 3HeT+ ions when one two nuclei T2 molecule...
Radiation chemical modeling of redox reactions biologically active compounds from plant materials showed that coumarins possess strong antiradical properties. Data confirming the radioprotective properties these were obtained. Antioxidant activity has been shown for specific medicinal extracts—Melilotus officinalis and Ledum palustre cormus. The radiation transformations revealed an unsubstituted coumarin greater activity.
ABSTRACTThe mass transfer parameters of Liquid Phase Catalytic Exchange (LPCE) column have been evaluated as a part conceptual design study water detritiation facility for JET. Height Transfer Unit (HTU), Equivalent to Theoretical Plate (HETP) and overall coefficient (KG) were tritium deuterium isotopic exchange between gaseous hydrogen liquid using the LPCE operated with same three-isotope mixture. The HTU KG deuterium. This indicates that in phase reaction limit rate column. However,...
A composite iodine sorbent was obtained in the form of porous polymer matrix with activated carbon particles impregnated triethylenediamine deposited on its surface. comparative assessment radioactive methyliodide capturing efficiency by and a sample industrial charcoal conducted. It shown that under selected testing conditions, hydraulic resistance is lower, sorption capacity higher than sorbent. method for comparing effectiveness sorbents, based calculation ratio index to minimum index,...
