| 摘 要： | 本文成功地制备了Eastman-AQ-55D聚合物修饰碳纤维电极,用循环伏安法探讨了一些实验参数的影响,并对Ru(NH3)63+、甲基紫精进行了分析,结果表明,AQ-55D修饰的微电极稳定性好,修饰方法简单,灵敏度和选择性都有一定的提高,Ru(NH3)63+、甲基紫精的峰电流与浓度在1.2×10-6～1.2×10-5mol/L、1.7×10-6～1.4×10-5mol/L范围内呈线性关系,其相关系数分别为0.999、0.998.利用此电极测定了几种离子在膜中的扩散系数.

| Abstract: | Acarbon fiber electrode modified with Eastman-AQpolymer film was successfully prepared, effects of some experimental parameters were assessed.The behavior of (Ru(NH3)63+ and MV2+(methyl viologen) were investigated by cyclic voltammetry.AQ-55Dmodified microelectrode possesses high stability, selectivity and sensitivity, the linear ranges of Ru(NH3)63+ and MV2+ are 1.2 ×10-6- 1.2×10-5 mol/Land 1.7×10-6-1.4×10-5 mol/L, and the correlation coefficients are 0.999 and 0.998, respectively.Diffusion coefficients of some ions in the film were determined by chronoamperometry at AQcoating microdisk electrode. |
