- 中文摘要: The uranyl chelate of ferron was investigated polarographically over the pH range 1.98-10.00 and ligand concentration 0.005-0,060M. A reversible and diffusion controlled reduction wave was obtained, however, when ferron concentration below 0.02M and pH below 5.0, it became irreversible. The chelate species identified were UO2(HA)2 at pH range 2.5-7.1 and UO2(OH)(A)… over pH 7.1. the electron-transfer coefficient, rate constant, diffusion coefficient and activation energy of reduction process were determined.
