| 摘 要： | 制备了多壁碳纳米管修饰玻碳电极,采用循环伏安法(CV)研究了盐酸氯丙嗪在修饰电极上的电化学特性,发展了一种新的检测盐酸氯丙嗪的电化学分析方法。在最佳实验条件下,用循环伏安法检测盐酸氯丙嗪,其响应电流与盐酸氯丙嗪的浓度在8.0×10-5~1.0×10-3mol/L范围内有很好的线性关系,线性方程为Ip(A)=0.0106c(mol/L)-8×10-8(R2=0.999,n=6),检出限为6.2×10-6mol/L(S/N=3)。方法可用于盐酸氯丙嗪片的测定。

| Abstract: | A new method for the determination of Chlorpromazine Hydrochloride at the carbon nanotubes modified glassy carbon electrode was described. The electrochemical characteristics of chlorpromazine hydrochloride at this modified electrode were studied by cyclic voltammetry in detail. Under the optimal conditions, the method showed good linearity for chlorpromazine hydrochloride in the range of 8.0×10~(-5)～1.0×10~(-3) mol/L in 0.05 mol/L H_2SO_4 with a detection limit of 6.2×10~(-6) mol/L (S/N=3). The proposed method showed high selectivity and sensitivity, and the disposal method of the sample was simple. The method was applied to the determination of chlorpromazine hydrochloride tablets. |
