The product of the Molybdenum-99 purification process, obtained from Uranium-235 fission products, has a degree of purity of 90%-95%, which its present active and inactive impurities are destructive reducing the efficiency of 99mTc/99Mo generators. As an alternative to the common sublimation method, indirect sublimation could increase purity and reduce molybdenum loss. In this method, the molybdenum in the product will be absorbed by passing through the alumina column and then the dried absorbent will be sublimated. In the present study, the effective factors in molybdenum absorption such as the amount of adsorbent, and the volume and flow rate of the input solution and molybdenum were optimized. The final absorption efficiency reached 97-99%. This investigation is expected to be applied to molybdenum-99 production.
