Sorption of rhenium and uranium from solutions

| Реферат |
Intensive researches on extraction of rhenium from solutions of underground leaching of uranium-bearing ores have been carried out in recent decades. However, publications are devoted primarily for development of technologies from industrial solutions. Information on theoretical researches is very limited. Nowadays, there were established the regularities of rhenium and uranium sorption from solutions of their joint presence by highly basic anion exchangers A920 and AMP, used in sorption technology for uranium extraction. It is interesting to identify the regularities of rhenium and uranium sorption from solutions of their joint presence by weakly basic anion exchangers. Application of weakly basic anion exchange resins (where rhenium can be desorbed by ammonia), will simplify the existing technology of rhenium recovery in uranium industry. This article shows the results on sorption of rhenium and uranium from solutions of their joint presence by weakly basic anion exchanger A170. Under the static conditions, there were studied the influence of salt form of anion exchanger (sulfate, chloride, nitrate, hydroxide), nature of sulfate, nitrate and chloride-containing compounds (acid, sodium and zinc salts), carbonic acid salts, and their concentration (1–1000 mol/m3) on sorption capacity of metals. There was found that metals were recovered from studied solutions by anion exchanger A170 differently. Sorption of rhenium is good and stays almost in the same level. Good and equal anionite rhenium sorption from any solution is in salt forms of mineral acids, while bad anionite rhenium sorption is in hydrated form. Nature of nitrate and chloride compounds (in contrast of sulfate) has an identical effect on sorption capacity of rhenium. Moreover, increase in their concentration has a significant suppressive effect on rhenium sorption. Nature of sulfate-containing compounds and their concentrations have different effects on rhenium sorption, while, to a lesser extent, their concentration suppresses the sorption of rhenium in comparison with nitrate and chloride-containing compounds. Uranium is well sorbed only by sulfate form of anion exchanger and only from sulfate solutions and weakly concentrated carbonate compounds. Different sorption capacity of metals is explained in terms of their ionic state in solution. |
