As water pollution continues to be a global concern, there is a demand for cost effective remediation technologies. A large contribution of water scarcity can be traced back to heavy metal ion contamination which current technologies, such as ion exchange or ‘softening’ have proven to be ineffective. This work focuses on the remediation of heavy metal ion pollutants using the incorporation of β-Cyclodextrin (β-CD), and conductive polymers into an adsorbent, cellulosic nanocomposite. Previous results have shown that β-CD can enhance the adsorption capability allowing the removal of 75% Cadmium (Cd) ions from solution. To further increase the yield of metal ion removal, the chemical polymerization of a conductive polymer, such as polyaniline (PANI) introduces electrochemical properties to the cellulosic film. Initial results have indicated that with the application of voltage these conductive nanocomposites have the ability to be used for the electrochemical treatment of simulated wastewater as Copper (Cu) ions were shown to be successfully removed from solution.
