Abstract
Time-resolved laser-induced fluorescence is a unique method for direct uranium speciation at low level in the framework of environmental stu dies. By varying pH and uranium concentration in the absence of carbon ate ions and at fixed ionic strength, it was possible, together with f ree uranyl UO22+, to identify spectrally and temporary all the uranium -hydroxo complexes, namely, UO2OH+, UO2(OH)(2), UO2(OH)(3)(-), (UO2)(2 )(OH)(2)(2+), (UO2)(3)(OH)(5)(+), and (UO2)(3)(OH)(7)(-).
