项目摘要
A growing
number of recalcitrant pollutants of human health and environmental concern are
entering Canadian and global water and wastewater systems at alarming rates.
While conventional water and wastewater treatment technologies are effective at providing clean, usable water, these methods are
insufficient to remove emerging aquatic contaminants. 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
environment, and adding innovation to the Canadian water industry.
