• 中文摘要： The complex species of UO2(HA)(H2A)+ and UO2(HA)2 were identified in the ascorbic acid solution of uranyl ion at pH<2.1 and pH>2.1, respectively. Polarographic wave was proved to be the simultaneous reduction of UO..+2 and UO2(HA)(H2A)+ at pH<2.1. However, at pH>2.1, the wave is due to the reduction of UO2(HA)2. the stability constants of the two complex species were found to be 5.1×10.. and 1.0×10.., respectively. the hydrolysis constant of uranyl ion the solution of ascorbic acid was determined.
