Abstract

In order to work out a system of a complex catching of such gases as UF6, HF, BrF3 there has been made a study of the sorptional processes on solid absorbents, such as Al2O3, Ca(OH)2. As a result Br2 is produced in these processes. That's why the study of catching Br2 on such sorbent as NaX has been made. On interaction in the system Al2O3 - UF6 with the indoor temperature the process of physical adsorption prevails. The increase of the temperature till 423 K lead to a complete quantitative absorption of UF6. X-raying and phase analysis of the reaction products showed that all uranium is in the form of oxides, and aluminum is the form of AlF3. On interaction in the system Ca(OH)2 - UF6 the absorption of UF6 can be already observed with the indoor temperature, and UO2F2 and CaF2 are the solid reaction products in this case. The study in the system Al2O3 - BrF3 showed that chemical interaction is observed qualitatively with the indoor temperature. The ration of AlF3 and AlOF is 40/60 in the solid reaction products. Interaction in the system Ca(OH)2 - BrF3 is also observed with the indoor temperature. The solid reaction product contains CaF2. In gaseous interaction products - BrF3 with Al2O3 and Ca(OH)2 - Br2 and H2O are contained. When the temperature is 400-423 K the presence of HF can be observed.
