摘要:

The sorption behaviour of the radiotracers Eu9+, 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.
