摘要
制备了多壁碳纳米管修饰玻碳电极，采用循环伏安法（CT）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。
A new method for the determination of Chlorpromazine Hydrochloride at the carbon nanotubes modified glassy carbon electrode was described. The electrochemical characteristics of chlorprornazine hydrochloride at this mod- ified electrode were studied by cyclic voltammetry in detail. Under the optimal conditions, the method showed good linearity for ehlorpromazine hydrochloride in the range of 8.0 × 10-5 - 1.0 × 10-3 mol/L in 0.05 mol/L H2SO4 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.
