Nanoparticles can be made from a variety of metals. The nanoparticles can bind to or adsorb metal ions to remove them from solution due to the properties at the nanoparticle surface. Specifically in our study, we focus on iron oxide nanoparticles and the hydroxide groups on their surface that allow the adsorption of silver, lead, and copper from solution. The comparison of each adsorption by measurement of a decrease in concentration in the solution allows us to determine which is absorbed the best and to investigate what causes the adsorption to occur. In order to determine the amount of metal removed from solution by the nanoparticles, we utilize atomic absorption (AA) spectroscopy. This allows us to compare which metal was removed best by the nanoparticles through comparison of initial absorbance of the metal solution versus the absorbance of the solution after nanoparticles were introduced and filtered out. We investigated why this removal could occur. Redox, precipitation, and adsorption were investigated as possible explanations. With the help of experiments involving redox potentials, pH, supernatants, and adsorption efficiency we were able to determine the main reason for removal of metal cations from solution by iron oxide nanoparticles was adsorption. |
