Rapid determination of strontium-90 in seawater

Abstract

It was shown, that preconcentration of ⁹⁰Y from seawater by Y₂O₃, YF₃, LaF₃ and CeF₃ is possible. YF₃ is the best of all from this viewpoint, because it don’t adsorbs the radioisotopes of Pb (II) and Th (IV). The interference of ²¹⁰Bi can be eliminated by preconcentration its on PbS. Measurements of ⁹⁰Y by Cherenkov radiation without its elution from column was suggested.
