Othmane, G. Uranium speciation, controlled by biotic and abiotic factors, represents a key parameter for the control of uranium transfer in the environment. This study firstly deals with uranium speciation in opals from the Nopal I uranium deposit Mexico. Microscopic observations of opals at the nano-scale revealed the occurrence of vorlanite, cubic CaUO 4. This was the first time this rare calcium uranate has been found displaying a cubic morphology, in agreement with its crystal structure.
Nopal I opals have been further investigated through time-resolved laser fluorescence spectroscopy. The opals spectra and their comparison with those of experimentally produced standards indicate occurrence of mono- or polymeric uranyl complexes associated or not with calcium or phosphate sorbed onto internal surface of opal around pH Finally, the speciation of uranium was studied in mill tailings from Gunnar Canada.
In the first tailings site, uranium primarily occurs as monomeric, inner-sphere uranyl complexes sharing edges with Fe O,OH 6 octahedral sites of iron-oxy-hydroxides and chlorite. Our results suggested that U VI co-precipitates with iron oxy-hydr oxides predominate in the second tailings sites. Who was the man in question, Gunnar Källén ?
His appearance in the physics sky was like a shooting star. His contributions to the scientific debate caused excitement among young and old. Similar to his friend and mentor, Wolfgang Pauli, he demanded honesty and rigor in physics - a distinct dividing line between fact and speculation.
