The dissolution of uranium was investigated from contaminated sediments obtained at the US. Department of Energy (U.S. DOE) Hanford site. The uranium existed in the sediments as uranyl silicate microprecipitates in fractures, cleavages, and cavities within sediment grains. Uranium dissolution was studied in Na, Na-Ca, and NH4 electrolytes with pH ranging from 7.0 to 9.5 under ambient CO2 pressu...
Two mononuclear U02(VI) complexes of the general formula [(HL)U02(OH2)2] О.бШО, where L is a pentadentate N2O3 asymmetric Schiff base ligand, were synthesized and used as ligands for further coordination of either Cu(II) or Ni(II) ions. The U02(VI) ion occupies the outer O2O sites of the ligands, thus leaving the inner N2O2 sites of the ligands vacant for further coordina tion. Different types...
Influenced by different cations in the self-assembly of chiral units, achiral (UOC-NH4, UOC-Ca) and chiral (UOC-Na) uranyl-organic compounds were obtained from achiral reactants. The photocatalytic activity of UOC-Na was also investigated.
Discrete aqueous metal oxide polyionic clusters that include aluminum polycations, transition-metal polyoxometalates, and the actinyl peroxide clusters have captivated the interest of scientists in the realm of both their fundamental and applied chemistries. Yet the counterions for these polycations or polyanions are often ignored, even though they are imperative for solubility, crystallization...
