Study of Utilization Alumina for ⁹⁹Mo and ¹³¹I Separation from UO₂（NO₃）₂ Solution

Alumina（Al₂O₃） can be used for the extraction of MoO₄^2- and from UO₂（NO³）² soluTion.can be reduced to by using Sodium sulphite,then MoO₄^2- and IO₃^- can be separated with Al₂O₃ for the unadsorption of I^- on Al₂O₃.The total recovery yield of Mo and I is 78.3%±7.00% and 87.9%±5.48% respectively,after MoO₄^2- and IO₃^- in UO₂（NO₃）₂ solution were separated with two Al₂O₃ columns,and Mo in iodide products solution and I in molybdenic products solution meet the requirements.The results indicate that Al₂O₃ can be used for ⁹⁹Mo and ¹³¹I separation from the fuel of Medical Isotope Production Reactor.
