| Summary: | The wastewater treatment is a very important issue around the world, because if adequate water purification is performed, and reach the human being, could be harmful to health. Water contaminated with different substances or heavy metals, can cause illness and even death. Therefore, this scientific research sought to make membranes or nanometric mats by electrospinning process (electrospinning), with potential use as a filter for water containing copper. The mats are produced from solutions of polyvinyl alcohol (PVA) and Chitosan (CS) as a chelating agent to sequester metal ions, it also added a certain percentage of formaldehyde to prevent solubility in water of PVA. The nanofibers obtained were characterized by assays scanning electron microscopy (SEM), solubility, swelling, gravimetric efficiency, infrared spectroscopy Fourier transform (FTIR), differential scanning calorimetry (DSC) spectrometry. |
