Variación en el fraccionamiento de Tierras Raras en la materia en suspensión de la Ría de Huelva (SO de España)
Concentrations and partitioning of particulate rare earth elements are studied in an estuary affected by acid mine drainage. A sequential extraction procedure was applied to 14 suspended matter samples collected from four cruises. The results show that easy reducible fraction are mainly linked to LR...

| Resumo: | Concentrations and partitioning of particulate rare earth elements are studied in an estuary affected by acid mine drainage. A sequential extraction procedure was applied to 14 suspended matter samples collected from four cruises. The results show that easy reducible fraction are mainly linked to LREEs>MREEs=HREEs. The total concentration of REEs in the suspended matter varies according to the volume of the fluvial contributions that arrive at Ría, thus these increases significantly at the times of greater contribution |
