experiments were conducted to study the ability of surfactant-modified clinoptilolite for molybdate adsorption from aqueous solutions. clinoptilolite was treated with some cationic surfactants. adsorption of surfactants on zeolite surface was confirmed by chemical analysis, ir (infra-red spectroscopy), dtg (derivative thermogravimetry) and sem (scanning electron microscopy) techniques. the modi...

The reaction of a 100 Mo beam at 12 MeV/nucleon impinging on 4 He gas-cell target was performed. 99 alongside other coproduced isotopes were collected after the gas an aluminum catcher foil and their respective radioactivities measured by offline γ -ray analysis. In this contribution, preliminary experimental results which are used to discuss possibility optimal large-scale production condition...

This work reports the preparation of a Tc generator based on conversion of Mo produced by neutron irradiation, into insoluble magnesium Mo-molybdates compounds as matrix. The effect of magnesium salt types and concentration, Mg:Mo molar ratios, pH of molybdate solutions, eluate volume as well as the addition order of molybdate and magnesium solutions’ influences on the final Tc were evaluated. ...
