Interactions Of Ionic Liquids With Uranium And Its Implications On Biotransformation, Chengdong Zhang
Interactions Of Ionic Liquids With Uranium And Its Implications On Biotransformation, Chengdong Zhang
Dissertations
Room temperature ionic liquids (ILs) are pure ionic compounds with melting points below 100°C, which have drawn great attention due to their many unique properties. They have been widely used in organic synthesis, analytical chemistry, and biochemistry. Although ionic liquids have been used to extract metals and radionuclides, there is no systematic study on the interactions of ILs with uranium and their effects on the biotransformation of uranium.
My research focused on: (1) the interactions between uranium and ionic liquids in aqueous solution; and (2) biotransformation of uranium in the presence of ILs. The interactions between three representative ionic liquids, …

Study Of Organic Reactions In Pyridinium-Based Ionic Liquids, Ying Xiao
Dissertations
Recently, ionic liquids have attracted a lot of attention as novel materials for organic transformations. This is due to their unique properties, which make them suitable substitutes for organic solvents. Most of the available literature is focused on the application of imidazolium-based ionic liquids for organic reactions, while very limited information is available on the application of pyridinium-based ionic liquids.
In this study, two different ionic liquids, 1 -ethyl-pyridinium tetrafluoroborate ([EtPy]+[BF4]-) and 1 -ethyl-pyridinium trifluoroacetate ([EtPy]+[CF3COO]-) have been investigated. Compared to previous reports, the synthetic technique for preparation …
