Adsorption of Mo on γ-Al2O3 samples of various structures was studied with the aim of using these sorbents in production of chromatographic 99mTc generators. The sorption capacities of the oxides for Mo were determined. The optimal concentrations of HCl and HNO 3 for converting the sorbent to the H+ form were found. In all the cases, treatment with HCl ensures higher sorption capacity than treatment with HNO3. The sorption capacity of aluminum oxides prepared by ac electrochemical synthesis was studied in relation to pH of sodium polymolybdate solution and sorption time. The sorption capacity of these samples for Mo is several times higher than that of the chromatographic oxide traditionally used in the generator technology.
