| Abstract: |
| Low concentration rhenium from in-situ leaching uranium solution was separated with weakly basic D302-II resin. The results show that the separation coefficient of rhenium and uranium reaches maximum value of 7 965 in pH 2.0, and the absorption rate still reaches 94.35% when mass ratio of uranium to rhenium is 100∶1, which indicates that uranium in in-situ leaching uranium solution has no interference on adsorption and desorption of rhenium. 62.5 mg rhenium can be adsorbed in per gram D302-II resin, and rhenium concentration in stripping solution is 4.5 mg/mL desorbed from D302-II resin by 250 mL 3 mol/L NH4OH solution. White crystal NH4ReO4 can be obtained from stripping solution after evaporation and concentration |
