Abstract  

By means of Spicaria Violacea Abbott fungus, a microbiological method of concentration and separation of cobalt, iron and zinc is given. The influence of the experimental conditions, i.e. pH, time and concentration have been investigated.

Abstract  

The distribution coefficients of204Tl(III) between DEAE-cellulose and HCl-water-organic solvent (alcohols and ketones) mixtures have been determined using the statical method. The hydrochloric acid concentration as well as the nature and concentration of organic solvent in the mixtures have been widely varied. Sorption of Tl(III) takes place through a combined process of ion exchange and physical adsorption, its distribution between the anionic cellulose and solvent mixture depends on the tendency of the ionic association formation in these media.

Abstract  

Spicaria Violacea Abbott fungus was used as a microbiological collector for137Cs+,45Ca2+ and204Tl+ isotopes. The optimal conditions for the enrichment of these isotopes with respect to pH, time and concentration have been studied.
