title: [Chemiluminescence method for determination of dipyridamole].
abstract: A new system for the determination of dipyridamole with flow injection chemiluminescence was described. It is based on the chemiluminescence reaction of dipyridamole-potassium permanganate with rhodamine B. Tween-80 was found to be an enhancer of the chemiluminescence reaction. A method based on the enhanced chemiluminescence for dipyridamole determination has been developed. The method has high sensitivity, selectivity and good repeatability with a linear concentration range of 5.0 x 10(-8) - 5.0 x 10(-5) g x mL(-1), a detection limit of 1.7 x 10(-8) g x mL(-1) and a RSD of 1.1% (n = 11, cs = 1.0 x 10(-6) g x mL(-1)).
