THE IMPACT OF URANIUM MACROIONS ON SOLUBILITY
The solubility of uranyl minerals impacts the mobility of uranium in contaminated sites, the genesis of these minerals in uranium ore bodies, and potentially the performance of a geological repository for nuclear waste. Over the past decade a large family of uranyl peroxide nanoscale cage clusters has been developed, which provides the opportunity to examine solid phase solubility in the presence of macroions. We have studied the solubility of solids containing uranyl cage clusters, as well as various uranyl minerals under aqueous conditions that promote cage cluster formation.
