Abstract: | A preconcentrating neutron activation method for determination of rhenium in rocks is described. The preconcentration is based on a preliminary extraction separation with acetone. The chemical recovery is determined by an isotope tracer technique using186Re. The method has been applied to the determination of rhenium in rock samples and extended to more complex systems. Rhenium content is in the range of 1 10 ppb. |
