Chemically modified graphene-like carbon for the production of filtration membranes for industrial waste water purification

该项目的重点是开发用于净化工业废水的膜，该膜将来自3M加拿大公司先前开发的石墨烯类材料。对改进的过滤方法的需求，特别是那些针对去除潜在有毒和有害的过渡金属污染物的过滤方法，从来没有像现在这样大，因为大规模的工业过程，例如水力压裂（水力压裂）和沥青砂的提取，正在加拿大境内产生大量的污染水。这项研究将着眼于将3M加拿大的石墨烯类材料转化为化学改性石墨烯和石墨烯氧化物过滤 具有可调孔隙率的膜。这项工作将帮助3M加拿大公司设计一种新的过滤膜系列，用于向加拿大和全球市场销售，根据各种工业废水流中存在的污染物，将不同的膜（具有不同的孔隙率）纳入产品中。拟议的研究将在西安大略大学和位于安大略伦敦的3M加拿大实验室进行。

The focus of this project is the development of membranes for the purification of industrial waste water, which will be derived from a graphene-like material that 3M Canada has previously developed. The need for improved filtration methods, specifically those that target the removal of potentially toxic and harmful transition metal contaminants, has never been greater as large-scale industrial processes, for example, hydraulic fracturing (fracking) and the extraction of bituminous sands, are generating immense quantities of contaminated water within Canada's borders. The research enabled by this grant will look at the transformation of 3M Canada's graphene-like material into chemically modified graphene and graphene-oxide filtration membranes with tunable porosities. This work will help 3M Canada design a new line of filtration membranes for distribution to the Canadian and global markets, where different membranes (with varying porosity) will be incorporated into products depending on the contaminants present in various industrial waste water streams. The proposed research will occur at the University of Western Ontario and within the laboratories of 3M Canada in London, Ontario.
