A luminol-potassium ferricyanide-perphenazine CL reaction with high sensitivity for the determination of perphenazine was found. A perphenazine molecular imprinted polymer (MIP) was synthesized. Using the perphenazine MIP as a recognition material, a novel molecular imprinting-chemiluminescence (MI-CL) sensor for the determination of perphenazine was made based on the luminol-potassium ferricyanide-perphenazine CL reaction. The sensor displayed good selectivity and high sensitivity. The linear-response range of the sensor was 5.0 × 10-8 - 1.0 × 10-5 g/ml with a linear correlation coefficient of 0.9961. The detection limit was 2 × 10-8 g/ml perphenazine and the relative standard deviation for 1.0 × 10-6 g/ml perphenazine solution was 3.7% (n = 11). The sensor was applied to the determination of perphenazine in urine samples with satisfactory results.
