The solubility of uranium(IV) hydrous oxide in sodium hydroxide solutions under reducing conditions
Description
The solubility of hydrous UO2 in sodium hydroxide solutions containing sodium dithionite and/or Zn metal powder as reductants has been measured. The results provide no firm evidence for any amphoteric behavior of U(IV) but do set an upper limit of K <= 2 x 10-23 for the hypothetical reaction: U4+(aq) + 5H2O<-->U(OH)5- + 5H+. The results provide no evidence for such a reaction. (author)
