Adsorption of metformin hydrocloride by ecovio® solution in electrospinning and activated carbon

The presence of medicinal products in the environment causes several changes in aquatic and plant life when present in surface water, wastewater and soil1. Metformin (Met) is marketed as metformin hydrochloride, an active ingredient for the treatment of type 2 diabetes mellitus2. The main impact caused by the presence of Met in rivers and lakes is the feminization of fish and small animals3. In order to remove this contaminant tested as adsorbents: ecovio® solution in electrospinning, (Figure 1), and activated carbon from the biomass of the Musa cavendish banana, in a batch process and quantified by Uv-Vis spectroscopy. The results showed which the highest rate of adsorption occurred for the actived carbon with KOH tratament, qexp. of approximately 53.28 mg.g-1, and modification of the ecovio® solution in electrospinning, using dichloro methane (DCM) as a solvent, increased its adsorption capacity by the increase of its porosity (Table 1). In future works, the activated carbon produced will be added to ecovio® solution in electrospinning and will be evaluate its mechanism and adsorption capacity.
