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)).
描述了一种用于测定双嘧达莫的流动注射化学发光新系统。它基于双嘧达莫 - 高锰酸钾与罗丹明B的化学发光反应。发现吐温 - 80是该化学发光反应的增强剂。已开发出一种基于增强化学发光法测定双嘧达莫的方法。该方法具有高灵敏度、选择性和良好的重复性,线性浓度范围为5.0×10⁻⁸ - 5.0×10⁻⁵ g·mL⁻¹,检测限为1.7×10⁻⁸ g·mL⁻¹,相对标准偏差为1.1%(n = 11,cs = 1.0×10⁻⁶ g·mL⁻¹)。
