研究了Ｅｕ￣（３＋）在ＥａｓｔｍａｎＡＱ－２９Ｄ化学修饰电极上的电化学行为。研究表明，在ｐＨ４．４的０．１ｍｏｌ．Ｌ￣１ＮａＣｌＯ＿４底液中，Ｅｕ￣（３＋）的还原一氧化过程是一种半无限状态；在最佳测试条件下，Ｅｕ￣（３＋）的还原峰高在１．０×１０￣７～１．０×１０￣（－５）ｍｏｌ·Ｌ￣（－１）范围内有良好的线世关系。用计时库伦法测定Ｅｕ￣（３＋）在聚合物涂层中有效电荷迁越的扩散系数Ｄ＿（ａｐｐ），其平均值为（３．２±１．１）×１０￣（－１１）ｍ￣２·ｓ￣（－１）。
The electrochemical behavior of Eu¯ (3+) at Eastman AQ-29D chemically modified electrode was studied. Studies have shown that 0.1mol at pH4.4. Under the optimal test conditions, the reduction peak of Eu ~ (3 +) is 1.0 × 10 ~ 7 ~ 1 .0 × 10 ~ (-5) mol · L ~ (-1) in the range of good lineage relationship. The chronometric coulometric method was used to determine the diffusion coefficient D app of effective charge transfer of Eu 3+ in the polymer coating with an average of (3.2 ± 1.1) × 10 (-11) m ~ 2 · s ~ (-1).
