Chemical Interfacial Reactions Affecting The Speciation And Solubility Of Uranium In Organic-Rich Environments, Carmen A. Velasco
Chemical Interfacial Reactions Affecting The Speciation And Solubility Of Uranium In Organic-Rich Environments, Carmen A. Velasco
Civil Engineering ETDs
The aim of this dissertation was to investigate the interfacial reactions between uranium (U) and natural organic matter NOM) affecting the solubility, adsorption, and precipitation of U in organic-rich environments. The chemical interactions between U and NOM are not well understood, which justified the following research objectives: 1) Identify the effect of pH on U speciation and the organic functional chemistry in mineralized deposits from the Jackpile Mine.; 2) Identify the precipitation of U(VI) and NOM as a function of pH (2, 4 and 7); 3) Identify changes in DOM chemistry due to the reaction of NOM and U at …
