Selenium is an essential trace element nutrient for human life, but it can be extremely toxic if taken excess. Various adsorbents have been applied for the removal of selenium from water but performed poorly in the removal of Se (VI), which is more bioavailable and more difficult to remove....

Fabrication of Graphene-based Nanocomposite Membranes for Treatment of Process-affected Water
DownloadSpring 2020
Membrane separation processes are extensively used for separation of solutes such as ions, colloids, macromolecules, and organic matter from water. Among various membrane technologies, ultrafiltration (UF) and nanofiltration (NF) are progressively being employed for elimination of organic matter...

Feather Keratin Derived Sustainable Biosorbents for Adsorption of Heavy Metal Ions from Water
DownloadSpring 2023
Water is the epicenter of sustainability and has an essential part of the existence and development of the ecosystem and socioeconomic pillars. However, one in every three humans does not have access to clean drinking water around the globe and heavy metal ions pollution is the major contributor....

Natural and anthropogenic inputs of arsenic and selenium to the environment in the Athabasca Bituminous Sands Region
DownloadSpring 2019
Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...

Omega-3 polyunsaturated fatty acids (n-3 PUFA) enriched eggs are an increasingly important contributor to the egg industry due to the health benefits of n-3 PUFA. During storage and cooking, n-3 PUFA could undergo oxidation and further cause cholesterol oxidation. This study examined stability of...

Regenerable Composites for Removal of Organic Dye in Aqueous Media and Water in Heavy Oil and the Associated Interaction Mechanism
DownloadSpring 2018
Water plays an indispensable role in all aspects of life, including farming, domestic and industrial uses. In industries, water has been extensively applied in mining, production and surface treatment, producing a large quantity of contaminated water that threatens human health, endangers...

The first chapter of this thesis describes the development of a general route for the generation of selenium stabilized carbanions via a method that bypasses acid catalyzed formation of selenoacetals. Aldehydes are first converted into α-hydroxystannanes by nucleophilic addition of Bu3SnLi. The...

Arsenic is a potent environmental contaminant and human carcinogen, occurring naturally in the earth’s crust and entering the food chain through leeching into the water supply. Upon entering the body, inorganic arsenic is methylated to mono- and di-methylated forms, the trivalent versions of...
