Adsorption Energy Evaluation from Luminescence Spectra of Uranyl Ions (UO22+) Adsorbed on Disperse Silica Surfaces

Luminescent measurements are utilized to evaluate the adsorption energy for hydrated uranyl groups on the disperse silica surface. The position of the UO22+ 0-0 electronic transition and the frequencies of intramolecular vibrations appearing in luminescence spectra were used in that evaluation. The method is based on the dependence of the adsorption bond… CONTINUE READING
