- 中文摘要: The uranyl ion in 5-sulfosalicylic acid (5-SSA) solution has been investigated by polarography. The constitution of the chelate species was confirmed by conductometric titration, under the experimental conditions: temperature 25.plmin.0.1C, pH=2.0-9. 0, ligand concentration 10-200mM. At pH<4.8, the chelate species UO/sub 2/(HA)/sub 2//sup 2-/ is predominant. At pH 6.0 the complex species UO/sub 2/(A)/sub 2//sup 4-/ mainly exists. The chelate species UO/sub 2/(HA)/sub 2//sup 2-/ and UO/sub 2/(A)/ sub 2//sup 4-/ co-exist between pH 4.8-6.0. The diffusion coefficients and stability constants have been determined by equations derived from Ilkovic equation.
