Nanomaterials, such as dendrimers, are currently being evaluated for new products because of their unique size, properties, and reactivities. Dendrimers can act as nanocontainers to entrap materials within the interior of their highly branched polymeric structure. We have developed a General Chemistry laboratory experiment that utilizes Generation 2-PAMAM-octyl surface dendrimers to entrap copper(II) ions. These dendrimers were able to transfer transition metal ions, such as copper(II) ions, from an aqueous solution into the non-polar solvent, dichloromethane. The transition metal was then released from the dendrimer structure by lowering the pH of the solvent mixture. The previous laboratory experiment provided a capstone activity that highlighted a variety of General Chemistry topics along with an introduction to Organic Chemistry. This project focuses on quantitating the copper(II) sequestration by these same dendrimers and would make an informative activity for an upper-division analytical chemistry project in an undergraduate curriculum. We have developed a method to quantitate the amount of copper(II) ions that are being bound by the octyl-dendrimer using ICP spectroscopy. This research project provides a quantitative assessment of the copper(II) ion binding capacity within the octyl-dendrimers and shows how nanomaterials could be a valuable tool for selective heavy metal remediation.
