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.
