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.

一些对人类健康和环境有影响的难降解污染物是
以惊人的速度进入加拿大和全球的水和废水系统。
虽然传统的水和废水处理技术在提供清洁、可用的水方面是有效的,但这些方法
不足以清除新出现的水生污染物。不像自然
正在发生的有机水生污染物,新出现的柠檬酸盐污染物必须
不仅可以从水系统中去除,而且可以降解。膜分离是目前最有效的技术,
净化水,但传统的膜缺乏污染物的机制,
降解许多环境污染物极易受到
侵蚀性氧化或还原降解。这是可以实现的电-
或催化增强的氧化和还原。
我的研究
旨在通过以下方式解决日益严峻的污染沃茨处理挑战:
在膜科学的新前沿--活性膜领域取得了领先的进展。我
先前的研究生产了导电聚合物纳米复合材料
膜能够进行高效和有效的水溶质分离,同时还表现出高的
导电性我建议在这一成功的基础上,创造出既能
分离和催化降解新出现的污染物。
我的研究
将重点放在三个方面的进步:1)这些小说的能力

水溶液中的有机污染物。的能力
这些用于还原降解模型芳族化合物的膜也将
测试,并将跟踪其还原转化副产品。据推测
施加交变电势会增强通量
通过防止表面污染和减少表面污染,
浓差极化2)开发先进的表面改性,
接枝到导电膜上的催化纳米颗粒

污染物,而导电膜将增强
这些催化剂的降解效率。3)挑战这些
具有含污染物的真实的沃茨的电催化活性膜
人类健康和环境问题。真实的沃茨包含各种
有机化合物,包括细菌,我们将研究
这些催化活性膜在降解难降解污染物的同时抵抗生物污染的能力。
这类膜的研究和开发将进一步拓展膜的应用领域
研究和使用将改善加拿大沃茨的质量,
废水,从而改善加拿大人的健康,保护我们的
环境,并为加拿大水务行业增加创新。
