Unlike naturally*occurring organic aquatic contaminants, emerging recalcitrant contaminants must*not only be removed from aqueous systems, but also degraded. Membrane separation is currently the most effective technology for*purifying water, but conventional membranes lack mechanisms for contaminant*degradation. Many environmental contaminants are highly susceptible to*aggressive oxidative or reductive degradation. This is achievable with electro-*or catalytically-enhanced oxidation and reduction.***My research*seeks to address the increasing challenges of treating contaminated waters by*leading advancements in a new frontier in membrane science – active membranes. My*previous research produced electrically conductive polymer nanocomposite*membranes able to perform efficient and effective aqueous solute separations, while also demonstrating high*electrical conductivity. I propose to build on this success and create active membranes able to both*separate and catalytically degrade emerging pollutants. ***My research*will focus on three areas of advancement: 1) the ability of these novel*electrically conductive membranes to electro-catalytically degrade model*organic contaminants in aqueous solutions. The ability of*these membranes to reductively degrade model aromatic compounds will also be*tested, and their reductive transformation by-products will be tracked. It is hypothesized*that an alternating applied electric potential will enhance the flux*of water across the membrane by preventing surface fouling and reducing surface*concentration polarization. 2) Developing advanced surface modifications using*catalytic nanoparticles grafted to the electrically conductive membrane*surfaces. These grafted catalytic nanoparticles will be able to oxidize organic*contaminants, while the electrically conductive membranes will enhance the*degradation efficacy of these catalysts. 3) Challenging these*electro-catalytically active membranes with real waters containing contaminants*of human health and environmental concern. Real waters contain a variety of*organic compounds, including bacteria, and we will study*the ability of these catalytically active membranes to resist biofouling while degrading recalcitrant contaminants. ***The study and development of such membranes will push the boundaries of membrane*research and their use will improve the quality of Canadian waters and*wastewater, thereby improving the health of Canadians, protecting our*enviro
