- 中文摘要: Uranyl chelate of 7-iodo-8-hydroxyquinoline-5-sulphonic acid (ferron) has been studied spectrophotometrically in aqueous solution at 25° and at an ionic strength of 0.1 M. the formation of this chelate was pH dependent, and the optimum pH range was between 5.4 to 5.9. Is mole ratio of ligand to uranyl ion was found to be 2 to 1 stoichiometry and the stability constant, log K, was determined as 13.32±0.08. By using the wave-length of 365 mμ, determination of trace amount of uranyl ion with the sensitivity of 0.54 γ/cm2 was possible.
