Production of microfluidic cells for uranyl phosphate dissolution studies to support phytoremediation strategies


EMSL Project ID
51805

Abstract

The objective of this limited scope proposal is to complete a set of micromodel experiments performed during a previous EMSL User Proposal that explored the citrate-promoted dissolution of uranyl-phosphate. Before this study can be published, one of the dissolution experiments must be repeated because it was interrupted by a power outage, and the starting uranyl-phosphate that was precipitated inside the micromodel had a different morphology than the starting material in the other experiments. This difference in the morphology of the uranyl-phosphate starting precipitate was not an isolated phenomenon even though an identical procedure was used to precipitate the uranyl-phosphate in the micromodels each time. Therefore, it is also necessary to determine the cause of these inconsistencies in the uranyl-phosphate morphology. In order to complete this objective, we require the construction of ten micromodel wafers from EMSL’s Subsurface Flow and Transport Laboratory. Since uranium is no longer permitted inside EMSL labs, the experiments will be conducted at Clemson University.
