Abstract:
Alumina(Al
2O
3) can be used for the extraction of MoO
42- and from UO
2(NO
3)
2 soluTion.can be reduced to by using Sodium sulphite,then MoO
42- and IO
3- can be separated with Al
2O
3 for the unadsorption of I
- on Al
2O
3.The total recovery yield of Mo and I is 78.3%±7.00% and 87.9%±5.48% respectively,after MoO
42- and IO
3- in UO
2(NO
3)
2 solution were separated with two Al
2O
3 columns,and Mo in iodide products solution and I in molybdenic products solution meet the requirements.The results indicate that Al
2O
3 can be used for
99Mo and
131I separation from the fuel of Medical Isotope Production Reactor.
