【摘要】 研究了聚中性红薄膜修饰电极对卡马西平的电催化作用,建立一种定量检测卡马西平的电化学分析方法。探讨了修饰电极性能对卡马西平的最佳响应条件,并初步推断了反应机理。在p H=5.03的PBS缓冲底液中,线性范围2.2×10-6mol/L~5.0×10-3mol/L(r=0.9986),检出限为5×10-7mol/L。该方法操作简单、灵敏,可用于实际药品测定。更多还原

【Abstract】 In this paper,an electroanalytical method has been developed to study the electrocatalytic activity of poly( neutral red)film modified electrode for the determination of carbamazepine. Electrochemical performance of this modified electrode and optimal response conditions for the detection of carbamazepine were discussed in detail.Experiments showed that the modified electrode kept a linear relationship with the concentration of carbamazepine in the range of 2. 2 × 10-6mol / L ~ 5. 0 × 10-3mol / L( r = 0. 9986),and the detection limit was 5×10-8mol / L. The modifing electrode was prepared with a simple method and had good performance.更多还原
