Preparation of Chemically Modified Cellulose Exchangers and their use for the Preconcentration of Trace Elements

SUMMARYA crosslinked poly(ethy1ene imine), using epichlorohydrin as crosslinker, was prepared and subsequently modified in order to obtain the corresponding N-methylated, N-carboxymethylated and N-phosphonomethylated derivatives. The sorption characteristics of these functionalized resins were studied by a batch equilibration technique, for uptake of Cu(II), Fe(II), Fe(II1) and uranyl ions from aqueous solution. Resins with tertiary amine or ammonium groups show negligible sorption for Fe(II), Fe(II1) and Cu(I1) at pH 1, in contrast with high sorption for U(VI), which is readily eluted with sodium carbonate. ZUSAMMENFASSUNG:Polyethylenimin wurde mit Epichlorhydrin vernetzt und anschlienend zu den entsprechenden N-Methyl-, N-Carboxymethyl-und N-Phosphonomethyl-Derivaten umgesetzt. Die Sorptionseigenschaften der funktionalisierten Harze fur die Aufnahme von Cu(11)-, Fe(I1)-, Fe(II1)-und Uranyl-(UO:+)-Ionen aus wasseriger Liisung wurden untersucht. Die Aufnahme von Fe(II), Fe(II1) und Cu(I1) bei pH 1 ist bei Harzen mit tertiaren Amin-oder Ammoniumgruppen vernachlassigbar, wahrend U(V1) leicht aufgenommen und mit Natriumcarbonatlosung ebenso leicht wieder eluiert wird.
