Preconcentration techniques for uranium(VI) and thorium(IV) prior to analytical determination-an overview.
TL;DR: Various off-line and on-line procedures developed for uranium(VI) and thorium(IV) prior to their analytical determination since 1990 were critically reviewed in terms of enrichment factor, retention/sorption capacity, validation using certified reference materials and application to complex real samples.
