Under acidic condition,the nitrogen atom in propantheline bromide was easily protonated and formed ion-complex with negative ion AuCl₄^-.The ion-complex was extacted with dichloromethane.When the ion-complex entered a reversed micellar microemulsion of cetyltrimethylammonium chlorine containing luminol,the dissociated AuCl₄^- reacted with luminol,producing an analytical chemiluminescnece signal.Under the optimum conditions,the linear range is from 0.001 to 10×10^-6 g/mL and the limit of detection is 0.04×10^-9 g/mL with a relative standard deviation (n=11) of ca.1.32% for 1.0×10^-6 g/mL propantheline bromide.The method has been applied to the determination of the studied drug in tablets and biological fluids successfully.
