Abstract
A great variety in retention properties occurs as a result of differen t methods of preparation of the sorbents. Specific surfaces and porosi ties, which are mostly connected with the sorption activities, may var y widely. The activation of Al2O3, SnO2 and silica get to produce high ly active sorbents occurs only if the oxide is contacted with acid imm ediately after thermal treatment. The efficiency of the separation sch eme has been tested using uranium and fission products under static co nditions from strongly alkaline aqueous solutions.
