Abstract
8-Hydroxyquinoline (8-HOQ) is known as an important chelating agent fo r several metal ions. This compound is practically insoluble in water. For this reason, in this study its water soluble sulfate salt has bee n used for complexing uranyl ions and the stability constants of the c omplex have been determined. The Irving-Rosotti method computing the C alvin-Bjerrum pH-titration data, was applied. Finally, the stability c onstants of the complex formed between (8-HOQN-H)2SO4 and uranyl ions were found to be IgK1=8.25 and IgK2=4.15, the overall stability consta nt being Igbeta2=12.40.
