85Sr as radioindicator has been applied to strontium separation selectivity study using cisdicyclohexano-18-crown-6 (DCH18C6) extraction agent and picric acid counter ion with the aim contribute development of a rapid method extraction. The same used for fractionation in chosen soils by application Tessier- BCR sequential procedures. Experimental results have shown, that mentioned system is app...
