摘要：

Chelating ion-exchangers on the basis of cellulose are described which are well suited for separation of uranium. The distribution coefficients for Ca2+, Cu2+, Fe3+, Ni2+, Pb2+, UO22+ and Zn2+ are determined as function of pH. The separation of uranium in a column filled with the cellulose-exchanger Hyphan is investigated in more detail. After preconcentration uranium is determined by energy dispersive X-ray fluorescence. For a sample of 5 l volume the detection limit is 0.3 ppb and the time needed for 1 analysis is about 3-4 h. This method of uranium determination is applied to various natural water sources from the Odenwald region (Odins forest). The results are discussed. © 1978 Springer-Verlag.
