In order to investigate the chemical form of vanadium in freshwater, an analytical method has been developed using 48V radiotracer which involves the absorption of the sample on Chelex 100 and Dowex 1-x8 columns followed by the selective elution of the different vanadium species and their assay by neutron activation analysis. Application of the method to identify the chemical species of vanadium in different freshwaters indicates that the element is present in tetravalent cationic and pentavalent anionic forms as well as in a neutral complexed form. The absence of the complex form in freshwater, collected in an unpolluted area, suggests that this type of vanadium could be an index of long-term pollution of freshwater.
