FIELD: chemistry.
SUBSTANCE: limiting specific weight of acid mL A, required for complete termination of its reaction with aluminium oxide is determined. The amount of acid mHCl required for treating aluminium oxide with mass mox is calculated using the relationship: mHCl=mL A·mOX. After making the corresponding calculations, aluminium oxide is treated with acid, put into a chromatographic column and a molybdenum solution is added.
EFFECT: more reliable operation of a technetium-99m generator in terms of prevention molybdenum from falling into the eluate owing to achieving maximum sorption capacity of the oxide used.
