The development of efficient adsorbents able to the treatment of groundwater is proposed.The design includes using of natural-green and low cost raw materials of easy availability tocontribute to the solution of a real actual problem such as fluorine contamination in water forhuman consume. It is well known that the investigation of novel technologies to reachavailable water resources is increasing and the groundwater is in the focus. However, most ofthe studies are restricted to the model and centered in more (in appearance) dangerouspollutants (i.e. arsenic), misleading the impact of other species present in the matrix. In thiscontribution we have prepared nanocomposites based on natural zeolite and magnetite thatwas subsequently surface modified with aluminum and calcium cations. The goal is toconfer specificity and functionality to these materials in order to be suitable for fluorineremoval. Finally adsorption assays have been performed using model aqueous solutions aswell as real groundwater samples to evaluate the performance of selected adsorbents.
