Abstract

Method of W separation from fission-99Mo solution was studied using alumina column and H2SO4/HNO3 eluents. The distribution coefficients of WO4 2− and MoO4 2− ions and the column loading/eluting conditions were investigated to optimize the separation process. 4–6 M H2SO4 solutions were successfully used to elute/separate 99MoO4 2− ions from the alumina column which strongly retained WO4 2− ions without significant W-breakthrough. The developed W/99Mo separation process is fit for being in-line incorporated/integrated in the alkaline dissolution-based process of fission-99Mo recovery currently used in LEU target-based 99Mo production.
