Physical And Chemical Interactions Affecting U And V Transport From Mine Wastes, Sumant Avasarala
Civil Engineering ETDs
This research investigates the physical and chemical interactions that affect the transport of uranium (U) and vanadium (V) from uranium mine waste sites by integrating laboratory experiments and reactive transport modelling with various spectroscopy, microscopy, and diffraction techniques. The document consists of results from three related studies. In the first study (Chapter 3), the reactive transport of U and V was investigated by sequentially reacting mine wastes collected from Blue Gap/Tachee Claim-28 mine site, AZ with 10mM NaHCO3 (7.9) and 10mM CH3COOH (3.4) during continuous flow through column experiments. Under both of these conditions (pH 3.4 and …
