Résumé : | During the last work, Access data base was created and used. So, for this research thesis, it has been updated and has currently 4394 samples. It has allowed to work on sample which contain rare earth elements in the groundwater and river waters. The main goal of this research thesis is to compare behavior of rare earth elements in the two hydrographic zones according some factors. The studied factors are the pH, the organic matter and redox potential. These have huge influence on rare earth elements behavior. Study was made on 525 samples from groundwater and 933 from river waters. This study shows that samples in the two hydrographic zones have overall the same behavior. Yet, rare earth elements in groundwater are more influence by pH (acidity). In the case of this elements in river waters, organic matter has major impact. For redox potential, only groundwater have been studied. |
