| 摘 要： | 研究了鸟嘌呤(G)在番红花红聚合膜修饰的玻碳电极上的电化学行为,发现SFR聚合膜电极对G的氧化能够起到明显的电催化作用。利用差分脉冲法研究了G在磷酸盐缓冲溶液中的线性关系,发现其浓度分别在6.0×10-7～1.0×10-5mol/L、2.0×10-5～7.0×10-5mol/L范围内与峰电流呈良好的线性关系。该电极用于实际样品的测定,回收率在97.1%～102%之间。

| Abstract: | The electrochemical behavior of guanine(G) at a poly(safranine T) modified electrode was investigated.It was found that the poly(SFR) modified electrode showed an obvious electrocatalytic activity for the oxidation of G.In phosphate buffer,the linear relationship between the peak current and concentration was studied by differential pulse voltammetrics(DPV) method.The linear ranges were 6.0×10-7～1.0×10-5mol/L and 2.0×10-5～7.0×10-5mol/L,respectively.The poly(SFR) modified electrode can be applied to the determination of G in tablet samples with satisfactory results.The recoveries were between 97.1% and 102%. |
