Sorption and desorption of molybdenum in alumina microspheres

The behavior of minor amount of molybdenum(VI) in the presence of large quantity of aluminium nitrate and separation of Mo(VI) from Al(III) with the aid of a chromatographic process onto an alumina column has been studied. The separation of both elements is in favor of the selective uptake of molybdenum by the alumina. The solution containing both elements is an acidified aluminium nitrate of high concentration in aluminium. The work envisage a future separation and purification of radiomolybdenum for the milking of technetium-99m. (author)
