dc.description.abstract | In an effort to develop new chelating agents for the decorporation of uranium and other actinides, the interaction of the clinically used 1,2-dimethyl-3-hydroxypyrid-4-one (Deferiprone or LI) with hexavalent uranium was investigated by using UV-VIS spectroscopy and solubility measurements. The complex stoichiometry estimation carried out by the Job plot method indicated that under normal conditions up to pH 8.0 a 1 [U(VI)]: I [L1] complex is formed. The stability constant of the UO2LI+ complex was determined by spectroscopic and solubility experiments and found to be log β11 =9.1±0.3. The molar extinction coefficient at pH 7.6 for the complex at 500 nm was estimated to be 650 ·mol-1·cm-1. At ligand concentrations higher than 6·10-410-4 mol·l-1 the formation of a precipitate was observed. The stoichiometry UO2(L1)2 was identified following FTIR measurements of the red precipitate and UV/VIS spectroscopy after dissolution. © 1999 Akadémiai Kiadó, All rights reserved. | en |
