Gi. Malofeeva et al., Preconcentration of cesium, cerium, cobalt, bismuth, and lead radionuclides by solid-phase extraction, J ANALYT CH, 56(3), 2001, pp. 238-242
A procedure was proposed for the preconcentration of Sr, Cs, Pb, Co, Bi, an
d Ce beta radionuclides by solid-phase extraction as ion-pair complexes in
the system dicyclohexyl-18-crown-6-sodium dodecyl sulfonate.
