Abstract
Several spectroscopic methods specially the time-resolved laser-induced fluorescence spectroscopy and the X-ray-absorption spectroscopy were used for the determination of the uranium speciation in plants. Differences between the uranium speciation in the initial solution and inside the plants could be detected. The chemical speciation of uranium is identical in the roots, shoot axis and leaf. It is independent from the uranium speciation in the initial solution and the type of the plant. The results indicate that the uranium is predominantly bound as uranium phosphate (phosphoryl) groups in the plants.
