Popis:	A chemiluminescence method for the determination of ω-chloroacetophenone in ethanolic extracts is elaborated. The method is based on the linearity of the concentration dependence of the intensity of luminol chemiluminescence upon the action of peroxide species forming in the reaction of ω-chloroacetophenone with air oxygen activated by hemin in alkaline solutions. The detection limit makes (1.0 ± 0.3) × 10−5 mg/mL (P = 0.95, n = 5, RSD = 32 %) at 293 K.
