| 摘 要： | 本文提出了铀(Ⅵ)-5-Br-PADAP-磺基水杨酸三元配合物的极谱配位吸附波。在pH为7.5-8.2的醋酸、三乙醇胺、乙醇底液中,该波的峰电位在-0.6855V(vs.SCE)。在1.00×10-7-1.00×10-5mol·dm-3范围内,铀(Ⅵ)浓度与峰电流呈线性关系。对极谱波的电流、电位性质进行了研究,测定了配合物的组成、表观稳定常数和离解及生成速率常数。

| Abstract: | A method has been elaborated which utilizes the adsorptive-complex polarographic wave of U(VI)-5-Br-PADAP-HO3SC6H3(OH)COOH in HAc-TEA-Et.OH medium. The peak potential is -0.685V vs.SCE at pH 7.5-8.4. The peak current is linearly related to the concen-tration of U(VI) in the range of 1.00 × 10-7-1.00×10-5mol·l-1. The behavior of current-potential curve was studied and the composition, stability constant(KKb) of the complex were determined. |
