Description

Sorption of thenoyltrifluoroacetonates of rare earths on polymeric sorbent (copolymer of styrene-divinylbenzene) containing the functional groups of macrocyclic polyether diazo-18-crown-6 is studied. Sorption capacity of a sorbent and sorption coefficients are calculated. It is shgown that Eu3+, Sm3+ and Gd3+ are sorbed most of all, and Ce3+, Pr3+, Yb3+, Lu3+ - worst of all. Luminescence properties of the sorption europium adduct is studied. The Eu detection limit in the sorbent is 0.00005 μg/ml, Sm - 0.01 μg/ml
