Description

The sorption behaviour of the radiotracers Eu3+, Co2+ and Cs+ by the sediment fractions: Sand, coars silt, fine silt and clay was investigated from aqueous solutions containing the complexing agents; humic acid, sodium phosphate or disodium EDTA. The effect of ligand concentration on the sorption of these elements by the sediment fractions was elucidated at varying pH values. The results obtained are interpreted in the light of the complex formation between the ligand and the metal cations beside the interaction between the ligand and the respective sediment fraction investigated. (orig.)

Abstract (German)

Es wurden die Sorptionseigenschaften der Radiotracer Eu3+, Co2+ und Cs+ durch die Sedimentfraktionen Sand, grobes und feines Schlemmkorn und Ton aus waessrigen Loesungen untersucht, welche die Komplexreagenzen Huminsaeuren, Natriumphosphat und Dinatrium EDTA enthielten. Der Effekt der Liganden-Konzentration auf die Sorption dieser Elemente durch die Sedimentfraktionen wurde unter verschiedenen pH-Werten ermittelt. Die erzielten Ergebnisse wurden vom Gesichtspunkt der Komplexbildung zwischen dem Liganden und dem Metallkation betrachtet; daneben wurden auch Wechselwirkungen der Liganden mit der jeweiligen Sedimentfraktion untersucht.
